US Patent 7783427 Combined runway obstacle detection system and method

An incursion detection system can be utilized with an aircraft. The incursion detection system can be utilized to determine a possible presence of obstacles associated with a runway, taxi-way, or other path of an aircraft. The incursion detection system preferably utilizes a sensor, such as a radar system, and a signal received on a wireless receiver. The wireless receiver can be part of an ADS-B system. A processing device determines a presence of at least one obstacle in a path based upon first data derived from the wireless receiver and/or second data received from the sensor.
