摘要:A method of detecting the division of a radar target (FL), for instance caused bythe release of a weapon from an aircraft which is tracked by a monopulse radar whoseantenna is aligned onto the target with the aid of azimuth and/or elevation differencesignals. Division of the radar target (FL) can be detected irrespective of whether thetarget is equipped with and uses an interference transmitter or not, by establishing asearch channel (SK) in the radar difference channels. This channel has a sensitivity which isvery low in a direction towards the tracked target, but which increases rapidly in

directions which deviate somewhat from the direction towards the target. The searchchannel can be established by comparison of the absolute values of the signal levels inthe difference channels with a threshold value.
