Is it Possible to Get a SAR Image of Ocean Waves Free of Spectral Cut-off by Direct Measurement

Abstract

Mikhail B. Kanevsky

A method of SAR sounding of the ocean surface is proposed, which is capable of providing an undistorted by spectral cut-off wave pattern. The method involves the use of two synchronized SARs, which look across the track line and illuminate the same area of the surface. Each SAR records its own backscattered signal, which are then multiplied with each other and the resulting signal is undergoing the procedure of matched filtering. Numerical estimates of the applicability conditions of the method are carried out.
