Abstract

A signal processing system is disclosed in which detected signals received from an antenna are mixed with computer-controlled first local oscillator signals, delayed, mixed with computer-controlled second oscillator signals, and retransmitted toward the hostile radar installation, characterized in that the delay is effected by a combined computer and microprocessor operation acting on the detected and mixed signal, the delayed signal being supplied to the signal transmitting branch via an IF gate that is operable by a computer-controlled microprocessor. The computer--which controls the operation of the local oscillators, the crossed field amplifiers, the tuned mixers, the delay switching system, the doppler correcting means, the core memory, and the microprocessor--is responsive to an amplified signal from the first mixer that is supplied to the computer via a pulse width and rate interval detector, and via a frequency discriminator that provides a reference frequency signal.
