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

摘要

Evaluation of the influence of aircraft landing lights on flight behavior of migrating birds at night has been completed. Birds do not make evasive maneuvers to avoid approaching aircrafts with their landing lights on. Evaluation of the AN/TVS-5 image intensifier shows that it is an ideal instrument to use in quantifying and monitoring bird migrations. The correlation between migration traffic rate and the density of bird echoes on the radar screen is identical on different nights when the magnitude of migration is the same. An automatic system composed of an image intensifier in combination with a closed circuit television video tape system has been developed to gather more accurate data on nocturnal migration.
