Low-Angle Radar Sea Return at 3-mm Wavelength

Abstract

Measurements of the radar return from the sea and targets on the sea were made at incidence angles near grazing with a 3-millimeter radar. The results show similarities in many respects to sea return at longer wavelengths, but they are strikingly different in a few instances. Notable are that the trend for cross section per unit area to increase with decreasing wavelength from 10 to 3 cm is not continued between 3 cm and 3 mm, and that the return for vertical polarization is substantially less than that for horizontal polarization for all conditions observed. Also included in the study are indications of angle, wind- speed, and boresight-wind-vector angle dependences of sea return.
