Intelligence, Surveillance and Reconnaissance

Intelligence, Surveillance and Reconnaissance

Refers to the collection and use of information from naval, joint, and national sensor systems in order to find, fix, and track both friendly and hostile forces and is a component of command, control, communications, intelligence, surveillance and reconnaissance (C4ISR) systems.

Intelligence, Surveillance, and Reconnaissance (ISR) systems are military operations intended to help decisions makers anticipate change, mitigate risk, and shape outcomes. The United States Department of Defense defines ISR as:

an integrated operations and intelligence activity that synchronizes and integrates the planning and operation of sensors, assets, and processing, exploitation, and dissemination systems in direct support of current and future operations.

ISR systems are at the intersection between military planning, operations, and assessment where intelligence is the product of surveillance and reconnaissance operations.

Definitions of ISR

Operation
Definition

Intelligence

Is defined as the product resulting from the collection, processing, integration, evaluation, analysis, and interpretation of available information concerning foreign nations, hostile or potentially hostile forces or elements, or areas of actual or potential operations.

Reconnaissance

Is defined as a mission undertaken to obtain, by visual observation or other methods, information about the activities and resources of an enemy or adversary, or to secure data concerning the meteorological, hydrographic, or geographic characteristics of a particular area.

Surveillance

Is defined as the systemic observation of aerospace, cyberspace, surface, or subsurface areas, places, persons, or things by visual, aural, electronic, photographic, or other means.

In ISR systems, which use a wide-array of platforms, sensors, and analytic capacity to create awareness, the principle function is to find, fix , and track both friendly and hostile forces. This includes assessing damage to hostile targets in an area of interest. In addition to ISR systems sensing as a collection, their function includes tasking sensors with the integration, interpretation, and exploitation of sensed information, either by way of analysts or operators or machine learning systems. Strike group ISR capabilities are provided by naval, joint, and national sensor systems which, in turn, can be space-based, airborne, on-the-surface, and subsurface.

ISR roles and responsibilities
Example of the joint layers of ISR systems.

According to joint military doctrine, the primary role of intelligence is to provide information and assessments to facilitate mission accomplishment. For instance, targeting an adversary's long-range missiles is easier when military commanders know where the missiles are. ISR works to inform these commanders to enable decision making. These systems and operators work to support military planning by anticipating adversary actions and defining the operational environment. ISR roles also includes warning friendly forces of threats, supporting deceptive techniques and counter adversary deception, identify adversary vulnerabilities, hold targets at risk of being attacked, and assess combat effectiveness.

These roles and responsibilities are accomplished through a detailed joint intelligence process that facilitates an understanding of the wide variety of intelligence operations and their interrelationships.

Artificial Intelligence and Machine Learning in ISR
The sensing grid OODA loop.

Developing ISR systems, also known as a sensing grid, plan to use artificial intelligence (AI) and machine learning (ML) to autonomously consolidate all-source information into a single operational picture, further exploiting big data in order to increase situational awareness. The all-source, fused picture is then used in conjunction with a command grid, a sophisticated AI to rapidly generate enemy courses of action for commanders to analyze, with further proposed capabilities including recommending courses of action and responses. This would further allow AI to sift through the large amounts of data collected by current ISR systems (let alone the data collected by proposed ISR grid systems). The current data rate challenges the limited number of analysts and can hinder the ability of timely responses to threats.

If realized, the strategy will see a sensing grid which enables a C2 system to observe, orient, and decide and act (OODA) at machine speeds, improving the chances of gaining a decisive advantage over an enemy.

CASPER

The development of smart software, by Raytheon, called Cognitive Aids to Sensor Processing, Exploitation and Response (CASPER) is intended to further lighten an operator's workload through automation tools. These aids are intended for integration into products like Multi-Spectral Targeting Systems, which provide visible and infrared intelligence and targeting information for an array of airborne platforms. The CASPER system would allow operators to focus on decision making rather than data processing, and, in turn, allow for a faster threat response.

Weaknesses

The use of AI within C2 and ISR systems also introduces weaknesses, which include being susceptible to deception or surprise (similar to a human analyst or decision maker), a lack of contextual understanding behind an ISR picture (at least until a "general intelligence" is achieved in AI), and, due to the use of datasets for patterns, a system will have to be specifically trained for the detection of important anomalies from adversary military systems. The datasets are also important, as AI would rely on these training sets for its prediction and probabilities, which means an adversary can develop capabilities for targeting specific AI vulnerabilities. These can include understanding and manipulating the algorithmic design or training data of an ISR AI.

Space-based systems

There are space-based image intelligence (IMINT), signals intelligence (SIGINT), and measurement and signatures intelligence collections systems (MASINT) in use in space-based ISR systems. These space-based systems are used for oceanographic and atmospheric intelligence, which includes variables such as surface wind and wave forecasts that are important for naval operations. And they offer forecasting services where other meteorological forecasting services do not provide the necessary information for naval, air, and surface operations.

IMINT

An IMINT system provides photographic coverage over denied territory that, through stereo photogrammetry, enables precise geodetic positioning of targets on the ground. These capabilities have provided the means for precision strikes against fixed targets. And, as the speed of tasking, collection, and processing has increased, the same capabilities have put relocatable targets at risk. Satellite constellations under the Future Imagery Architecture program of the National Reconnaissance Office offer greater imaging capabilities.

SIGINT

These systems have global coverage and provide geodetic positioning of platforms emitting at radio frequencies. Their product is quickly and widely broadcast to tactical forces afloat and in the field, where it is used for strike targeting and defense avoidance and suppression, among other purposes.

MASINT

Defense Support Program (DSP) satellites have for decades served as sentinels and early warning systems in the case of intercontinental ballistic missile launches. More recently, the infrared MASINT data from these satellites have been exploited to cue systems defending against shorter-range tactical ballistic missiles. In addition, the DSP ability to estimate launch points enables counterattacks against elusive Transportable Erector Launchers (TELs).

The Catalyst Space Accelerator (CSA), a startup accelerator sponsored by the Air Force Research Laboratory Space Vehicles Directorate, selected eight businesses to participate in their fall 2019 program which focused on space-based ISR.

Airborne systems

In the case of the United States Air Force, ISR has been a part of the divisions remit since its establishment as a separate military service. Since 2001, the U.S. Air Force has continued to support overseas contingency operations and fielded a massive theater ISR enterprise. The most visible part of the U.S. Air Force's ISR force is the over 425 manned and unmanned aircraft of 14 different types.

Examples of airborne ISR sytems.

The four unmanned aerial vehicles (the MQ-1B Predator, MQ-9 Reaper, RQ-4 Global Hawk, and RQ-170 Sentinel) are newer aircraft and total over 280 aircraft. The remaining types of manned aircraft date to the 1960s and 1970s These are the so-called Iron Triad of big-wing, manned ISR platforms (which include the E-3 Sentry, E-8 Joint Stars, and various OC/RC/WC-135s, totaling about 80 aircraft) which use airframes first developed in the 1950s. These aircraft are approaching their flight hour limits.

Next Generation ISR Dominance Flight Plan

Released on August 2, 2018 by Lt. Gen. "Dash" Jamieson, the Air Force Deputy Chief of Staff for ISR, the U.S. Air Force's Next Generation ISR Dominance Flight Plan outlines the intention to retool and increase both the quality and quantity of ISR production while simultaneously using fewer airmen. This suggests the plan depends upon the maturation of machine intelligence technology which would be provided through agile capability deployment. The further development of a collaborative sensing grid would include stand-off and penetrating, manned and unmanned airborne ISR platforms (with collaboration from space-based and cyberspace-based collection capabilities). And the proposal uses Publicly Available Information to build a foundation for information collected by classified ISR capabilities. And the plan further details the replacement of the manpower used to process, exploit and disseminate intelligence with machine intelligence systems in order for the U.S. Air Force to do more with less.

Surface-ship ISR systems
Example of ship-based radar, part of surface-ship ISR system.

The distinction between C4ISR and combat systems continue to blur with the advent of network-centric operations. Sensors onboard Navy surface ships are integral parts of combat systems, but with the data shared through other sensor systems and further data, a surface ship can have a more complete picture for the commander's situational awareness and increase the surface ship's combat capabilities. As part of this, new air defense radars have been developed as part of a multi-mission destroyer program planned to provide horizon and volume search through a dual-band (L and X) capability.

Further, the capability for a navy to deny or degrade an adversary's ability to find and target ships through the capability to suppress an adversary's ISR, either through physical destruction, deception, disruption, and corruption, will offer a critical edge: situational awareness and a reduced threat of attack. This has increased the development of offensive capabilities for Suppression of Enemy Intelligence, Surveillance, and Reconnaissance (SEISR). This is a similar system to the suppression of enemy air defenses (SEAD) which, through recognition of the increasing lethality of air defenses, works to suppress air operations of an adversary.

Subsurface ISR

Similar to surface or ship-based ISR systems, subsurface ISR systems, especially on nuclear propulsion attack submarines are employed for ISR in coastal regions and are part of a joint integrated ISR system. These subsurface ISR systems are especially capable at SIGINT and can take advantage of their covert nature to provide ISR while avoiding detection when necessary.

ISR in Cyberspace

The Chairman of the Joint Chiefs of Staff Joint Publication, Cyberspace Operations, works to define cyberspace ISR as:

ISR activities in cyberspace conducted to gather intelligence that may be required to support future operations, including offensive cyber operations (OCO) or defensive cyber operations (DCO). These activities synchronize and integrate the planning and operation of cyberspace systems, in direct support of current and future operations. Cyberspace ISR focuses on tactical and operational intelligence and on mapping adversary cyberspace to support military planning.

This definition captures the majority of the operations of Cyberspace ISR. However, these operations work to exploit, attack, and defend. They exploit cyberspace in order to collect intelligence about adversaries from the information that transits and is stored on their digital networks. It works to enable cyberspace attacks on adversary computer networks and work to defend their networks. These activities are supported by cyberspace intelligence preparation of the operating environment (C-IPOE) which provides an understanding of the cyber battlespace.

Activities in Cyberspace ISR

Activity
Description

Active cyberspace collection

Active cyberspace collection, also known as computer network exploitation, describes both enabling operations and intelligence collection capabilities to gather data from target computer systems, often achieved through taking advantage of flaws in network infrastructure and/or individual computer systems.

Multi-intelligence support for C-IPOE

This includes the reliance on the full range of intelligence disciplines, including: signals intelligence (SIGINT), geospatial intelligence (GEOINT), intelligence collection from human sources (HUMINT), and open source intelligence collection (OSINT).

Network Mapping

This works to break cyberspace into five layers: the identity, cyber-persona, logical, physical, and geographical layers. Information in any one of these layers can provide a linkage to enable further mapping of other layers.

Passive cyberspace collection

This is similar to human intelligence collection in which an agent may listen in on a conversation, which is more complicated but possible to do in cyberspace. While this collection can be relatively easy depending on the encryption and security levels of messages, but is often used as part of an active cyberspace collection, such as computer network exploitation (CNE) which offers a door through which a user can listen if undetected.

The data collected through cyberspace ISR activities is processed, and analyzed and becomes an analytical product called digital network intelligence (DNI). In turn, DNI becomes part of the larger ISR network grid to give operational commanders greater situational awareness.
