Abstract : Pulse Doppler radar systems are increasingly being used for airborne maritime surveillance roles, but current models for sea clutter do not incorporate the spectral information required to analyse the detection performance of these systems in the low grazing angle maritime environment. This report uses standard radar sea clutter models, and spectral information from wavetank and open ocean mea- surements to deduce the amplitudes, Doppler frequencies, and bandwidths of the Bragg, whitecap and spike components, which together comprise the sea clutter return.
