摘要： A system for sensing objects in the flight path of an aircraft and alerting the pilot to their presence includes a laser radar subsystem for emitting a beam of laser energy, receiving returns from objects, and processing the returns to produce range data related to the range of the objects from the aircraft. A scanning subsystem scans the beam and produces directional information related to the instantaneous direction of the beam relative to the aircraft. Processor circuitry controls operation, processes the range data and directional information with instrumentation data from the avionics system, produces video information related to the range, direction, and type of the objects, and interfaces the video information to the video display system. The processor circuitry may be programmed to (1) overlay video information on existing aircraft video display system, (2) provide acoustical warnings on an aircraft intercom, (3) analyze returns by subdividing the field of regard into a series of analysis windows, performing a statistical analysis of the returns related to each of the analysis windows, and identifying returns that fall into a common range interval, (4) transforming coordinates of objects measured relative to the aircraft to a horizon-stabilized, north-oriented coordinate system which is independent of the attitude of the aircraft, (5) inserting the coordinates of identified objects into a data base so that the coordinates may be used for constructing a video display at a later time and updating the data base to correct for movements of the aircraft, and (6) constructing a window-of-safety display of objects currently within the field of regard by adjusting the displayed position of the objects to compensate for avoidance maneuvers the pilot may execute.
