Sea-clutter dependency on windspeed
Abstract
The capillary wave effect on radar sea-clutter is discussed. The interaction between wind speed and these capillary waves is shown to be instantaneous and hence, is a first order effect which has an impact on various clutter characteristics. Computations to determine the average radar cross sections per unit area and the rms clutter velocity spread, both from experimentally derived constants, indicate that clutter cell size seems to significantly influence the statistical behavior of sea-clutter at horizontal polarization and is thus of vital importance in finding threshold levels for target detection.
