A new method for the simulation of coherent sea clutter

This paper describes a new technique for modeling and simulating the coherent returns from radar sea clutter, based on the compound K-distribution model for clutter amplitude statistics. Using observations of recorded Doppler spectra, a simple method is proposed for characterizing the temporal variations of the Doppler spectrum observed in a single range cell. It is shown that simulations based on this model can reproduce the main features observed in real measurements. These features include the asymmetry of the average power spectral density (PSD), the temporal variation of the local spectra and the increasingly spiky characteristics of the amplitude statistics observed in the extremes of the Doppler spectrum.
