Abstract

An adaptive nonlinear processor in which the desired radar signal together with an interfering signal is mixing with a voltage controlled oscillator and fed to a dispersive filter, the output thereof being detected and converted into gating pulses for enabling a gate circuit that is also fed by the same dispersive filter. The gated output is frequency inverted and fed to a second dispersive filter which produces an inverse Fourier transform. The signal is then mixed with the delayed output of the voltage control oscillator and band pass filtered.
