Emerging Unmanned Air Systems (UASs) are challenging current surface-to-air and air-to-air missile seeker capabilities. They are highly maneuverable and can sustain accelerations of 20 ‘Gs’ or more. Many are low observable and have active decoys as well as countermeasures (e.g., Russian Sukhoi S-70 and Chinese CH-7). The UAS flight envelopes can approach the performance of missiles so that there is less room for error in seeker performance. Swarms of UASs can overwhelm a defense system, especially when they are used in combination with decoys. Recently, the U.K. Royal AF demonstrated an autonomous swarm of unmanned aircraft with BriteCloud expendable active decoys. Also, AFRL is developing the Golden Horde Swarm program. For air-to-surface munitions, seekers face challenges that are just as imposing as swarms. Seekers must maintain accuracy with Camouflage, Concealment and Deception (CCD) used to mask targets as well as a complicated environment due to clutter and confusers in the scene. Robust Automated Target Recognition (ATR) is essential for identifying friend vs. foe and a prerequisite for precision strikes against tactical targets. Missile seekers using mmW radar (including multi-mode seekers) need improved signal processing capabilities to retain lethality against these new threats. We have outlined a processing approach that will drastically improve both the accuracy of airborne target identification and target lock in the presence of decoys and countermeasures. In addition, this approach can improve ATR using multi-sensor input for ground targets. We propose a solution for a low cost “common” multi-mode seeker that uses Open System Architecture (OSA) for use on the future Global Precision Attack Weapon (GPAW). The GPAW system will have a multi-mode seeker that utilizes GPS, UHF datalink, and laser designator to maneuver to the approximate location of the target. In this program, we address the performance of the seeker by employing a novel approach for processing of the mmW inputs. Our proposed solution is designed to reduce seeker and weapon cost by streamlining the software development and enabling dynamic, real-time laboratory testing of representative scenarios. ISL’s innovative solution directly supports the National Defense Strategy by providing “…Joint Lethality in Contested Environments.” In addition, it addresses the Air Superiority 2030 Flight Plan “…mix of capabilities to penetrate the highly contested environment as well as deliver effects from stand-off ranges offers a balanced approach to counter the A2/AD strategy.”
