AbstractA signal receiver employing constant false alarm rate (CFAR) circuitry is disclosed. The CFAR circuitry includes a dispersive delay line for stretching received echo signals, means for limiting the stretched echo signals and an inverse dispersive delay line for finally processing the stretched and limited echo signals. With delay lines of proper characteristics, the just-outlined processing of echo signals results in reconstituted signals, the amplitude of each one of such reconstituted signals being indicative of the source of a corresponding echo signal.
