ABSTRACT:
This invention relates to a system to alert an aircraft pilot of presence and general location of other aircraft that might constitute a collision threat to the pilot's aircraft. An antenna means operates in first and second modes characterized by respective first and second directivity conditions resulting in first and second gains for signals from a certain direction. Analysis means compares the amplitues of the first and second responses to produce an angle-indicating signal locating a potential collision threat without having to generate radio signals other than those already being generated by equipment in other aircraft in response to ground ATC interrogation.
