ABSTRACT:
An aircraft collision avoidance system is disclosed which presents target or threat information to a pilot using a pair of doppler radar transceiver systems directed orthogonally about and centered on the user aircraft's pitch plane to produce binaural audio tones that by their amplitude, frequency and phase difference allow the user pilot to visualize the location and closing rate of a potential target or threat, aurally, while maintaining an effective visual traffic scan.
