Characterising the Doppler spectra of high grazing angle sea clutter

Abstract

This paper characterises the Doppler spectra of radar sea clutter using data collected by the Ingara radar at grazing angles in the range 29° to 38°. It is shown that recently proposed modelling and simulation methods for lower grazing angles are still applicable for this data. The modelling method is also extended to capture the bimodal behaviour observed with high intensity returns from breaking waves looking up or downwind.
