ABSTRACT:
In a radar receiver, a distribution sensitive constant false alarm rate processor derives the clutter threshold level from the average magnitude of echo return signals. The threshold level continuously adjusts to the changing conditions of the radar environment and correctly corresponds to the false alarm rates which may be varied by the user of the host radar system. The clutter threshold is then used to suppress clutter returns following either a Rayleigh distribution or a Weibull distribution.
