Abstract
A circuit for use in anti-radar missile seekers or radar counter-measure eivers to convert the signals received from continuous wave radars into pulse signals so that the signals may be more readily detected and can be processed in the same signal processing circuitry used against pulse radars. The received signal is mixed with a frequency swept local oscillator signal, fed to a dispersive delay line and then detected.
