Abstract :
A possibility of recovering the wind vector over sea using an airborne radar altimeter in a short-pulse scatterometer mode, which has a nadir-looking wide-beam antenna with the modified beam shape forming an ellipse footprint, and in conjunction with simultaneous range Doppler discrimination techniques, is discussed, and a measuring algorithm of the sea surface wind speed and direction is proposed.
