Abstract
An aircraft collision warning system includes an optical detection system has a toroidal and conical field of view about the aircraft to detect near objects. The detection system utilizes thermal detection in a passive mode. Optionally, the detection system also includes radio frequency (RF) elements to form a directional radar for improved object detection confidence. The radar is used in either a passive or active mode. The detection system includes a detector array to detect light from the toroidal-shaped and conical-shaped airspace. Data from the detector array is accumulated and analyzed for objects. Upon object detection, the object is tracked, kinetically assessed for collision with the aircraft, and reported to the pilot and/or auto-pilot system. The detection system is configured as a non-cooperative system that stares into the toroidal and conical field of view.
