ABSTRACT:
Satellite radar apparatus measures the backscatter coefficient of the sea to determine the speeds and directions of winds at sea. The apparatus implements three aiming directions per swath with the track thereof on the Earth being parallel. The radar technique used operates by pulse compression, and on reception noise is measured in parallel with the measurement of signal plus noise. The apparatus includes an assembly for calibrating the product of transmission power multiplied by reception gain, which assembly includes a servo-control loop connected to the transmission line via a directional coupler.
