Abstract

A system which in response to a received signal, alters the transmit chareristics in a manner that cannot be predicted by any enemy attempting to jam the target detecting device and has no effect on the inherent probability of detecting a target. Any signal passed by the threshold of the receiver is processed and fed to the pulse repetition frequency generator and will randomly change the pulse repetition frequency of the transmitted signal.
