Results from a French navy (SHOM) study to retrieve waves in limited depth. Wave spectra derived from Advanced Synthetic Aperture Radar (SAR) images acquired by Envisat in narrow swath mode were compared to insitu measurements by seven sensors, deployed in a field experiment carried out on the French coast of the English Channel. Under the low to moderate wind speed observed conditions, overall good agreement were found between in-situ and ASAR observations, over a wide range of wave heights and directions, including waves propagating in the radar azimuth direction, and incidence angles different from the standard wave mode products.
