ABSTRACT
Analyses of sea spikes are presented for data measured at low grazing angles using a high-resolution X-band radar. To investigate the spikiness of sea clutter at different range resolutions, several analyses and statistical modelling were applied to measured sea clutter data with different resolutions and polarizations. The results show that the spikiness of sea clutter increases as the range resolution becomes finer.
