Aerospace Instrument-Making Annotation << Back Airborne radar altimeter as a sensor of the wind speed and direction over the sea surface A.V. Nekrasov The possibility of the vector of velocity and direction of wind over sea measuring with the help of an airborne radar altimeter as a scatterometer with a nadir-looking wide-beam antenna in conjunction with simultaneous range gating and Doppler discrimination techniques is discussed, and measuring algorithm of sea surface wind speed and direction is proposed.
