Abstract : The patent describes a system for preventing an ECM receiver employed to intercept enemy signals and to set a jamming transmitter to the same frequency from being subject to interference by its own jamming output. By blanking the jamming signal during the receiver CRT sweep interval, and negating every Nth blanking pulse, both the enemy's signals and the jamming signal are simultaneously displayed for monitoring, the former being visible through the latter so that any interruption or frequency shift in the enemy signal is readily detectable.
