Spike statistics features of the radar sea clutter in the millimeter wave band at extremely small grazing angles

Spikes of the scattered signal with specific statistical features are observed even for large grazing angles in addition to the range continuous signal. The strict physical model of the spikes is absent and this does not permit one to explain their statistics. It is noted only that the spike spatial statistics are associated with the breaking sea waves and foam presence on sea surface. In this paper the problems of the spike radar characteristics for frequency band of 10-140 GHz are considered.
