Advances in radar performance modelling in sea clutter

Recent advances in the understanding and modelling of sea clutter are summarised, based on the work of NATO panel SET-185. This work has considered clutter observed at medium grazing angles, typically in the range 10° to 50°. New assessments have been made of reflectivity, amplitude statistics and Doppler spectra. These results have also been used to investigate different target detection techniques suitable for medium grazing angle sea clutter.
