Abstract :
Recent research suggests that it may be possible to measure both wind speed (magnitude) and direction over the oceans with a passive microwave sensor operating in the 18-37 GHz range. Published data suggest that the optimal measurement of direction would be made with the cross correlation function <EvEh*> and a 360 degree conical scan. These are measurements ideally suited to a synthetic aperture radiometer. Preliminary studies indicate that a sensor system of this type would meet nominal measurement requirements and could be packaged compactly enough for launch on a PEGASUS/TAURUS class vehicle
