Further Results on the Detection of Targets in Non-Gaussian Sea Clutter

A recent work calculated the probabilities of detection and false alarm for the mean and median detectors for the log-normal and contaminated-normal descriptions of sea clutter. This correspondence extends the previous work by first calculating the performance of the trimmed-mean detector and then calculating the detection performance of all three detectors when the target exhibits Rayleigh fluctuations. Finally, a simple example is used to show that the optimal beamwidth of a radar need not be the smallest obtainable beamwidth.
