Measurement of the wind vector over sea by an airborne radar altimeter, which has an antenna with the modified beam shape

In this paper, 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 egg-shaped 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.
