This invention relates to radio detection systems and more particularly to short range detection systems useful on aircraft for detecting and tracking down enemy aircraft.
In aerial navigation particularly in combat areas during war time under conditions where enemy aircraft is not easily observed by the pilot because of distance, clouds, fog Or the blackness of night or because the enemy craft is in the sun, great need exists for some form of compact, light weight, radio detection apparatus. Such detection apparatus is also desirable in peace time flying to avoid collision with other aircraft and for detection of obstacles such as mountain peaks.
It is an object of my invention to provide a radio detection system to satisfy the foregoing needs.
Another object of my invention is to provide a method and means for detecting the nearest obstacle to an aircraft in flight.
Still another object of the invention is to provide a method and means for detecting the presence and the distance to other aircraft and obstacles within a given detection range of an aircraft equipped with detection apparatus'according to my invention.
