Abstract :
A method for simulating coherent sea clutter has been adapted for Pareto distributed clutter by using an inverse gamma distribution for the local clutter intensity. The model is applied to the range variation of Doppler spectra from Pareto distributed clutter collected at grazing angles of 31°-37° with the DSTO Ingara radar. The model produces Doppler spectra with a Gaussian shape that vary with range in a similar way to those obtained from the data. The simulations contain clutter spikes that replicate the properties of real sea spikes in respect of their intensity statistics, Doppler spectra and position near the wave peaks.
