ABSTRACT:
An improved receiver for a non-coherent radar system including a mixer, an intermediate frequency amplifier, an envelope detector and a sliding window integrator. The receiver further includes a circuit connected to the sliding window integrator for providing enhanced signal-to-clutter ratios and azimuth resolution. The circuit comprises a pair of cascaded inverse filters wherein the first inverse filter compensates for the filter response of the sliding window integrator, and the second inverse filter compensates for the filter response of the radar system antenna due to its gain pattern.
