Abstract : The patent describes a method and apparatus for detecting targets in high sea states and sea clutter. A comparison is made of a stored representation of doppler spectrums from sea returns free of targets with instantaneous statistics of sea clutter doppler to determine the presence of a target. Radar return pulses are fed through range gates and filters to produce a spectrum of signals corresponding to distributed ranges from the radar. The spectrum of signals is compared with the stored doppler spectrum in a variance analyzer to produce an output when a target signal is present.
