Abstract

Previous analysis of Advanced Synthetic Aperture Radar (ASAR) signals collected by ESA's Envisat has demonstrated a very valuable source of high‐resolution information, namely, the line‐of‐sight velocity of the moving ocean surface. This velocity is estimated from a Doppler frequency shift, consiste...
