Radar Techniques for Air Force Applications in Avoidance of Bird- Aircraft Collisions and Improvement of Flight Safety

During the year three major objectives were accomplished an evaluation of airborne radar systems for possible detection of birds aloft, an evaluation of the FAA airport surveillance radar ASR-4 for monitoring bird movements in the vicinity of airports, and an evaluation of the precision approach radar PAR or ground control approach GCA radars for monitoring bird movements through airport landing corridors. The precision approach radar or ground control approach radar along with the airport surveillance radar were found to provide all the necessary data to avoid birdaircrarft collisions. Furthermore, the flight controllers are in contact with the pilots and can warn them of dangerous concentrations of birds in their flight paths.
