Precision Direction Finding of Radars from an Airborne Platform

Lavanya Ganesh

Abstract: Electronic warfare is the military use of electronics to prevent or reduce an enemy's effective use and to protect friendly use of electronic radiation equipment. In precision direction finding of radars from an airborne platform, the method used is very simple and efficient. By finding the rate of change of phase difference, the direction of the ground based radar can be found from the aircraft. The aircraft consists of antennas on its wings and it receives the signals which are transmitted by the ground based radar. First, the path difference between the antennas and ground based radar is found. From the path difference values, the phase difference is found for each time intervals. Rate of change of phase difference is obtained by finding the difference between two successive phase difference values with respect to a particular interval of time.

Keywords: PATH DIFFERENCE, PHASE DIFFERENCE, ANTENNA
