WebHow does a satellite scatterometer work? A radar scatterometer operates by transmitting a pulse of microwave energy towards the Earth’s surface and measuring the reflected energy. A separate measurement of the noise-only power is made and subtracted from the signal+noise measurement to determine the backscatter signal power. WebThe scatterometer does not directly measure the wind. Rather, it measures the normalized radar backscatter (s o) of the surface. Then, from multiple s o measurements, the wind blowing over the ocean's surface is inferred. Scatterometer wind measurements have wide application in air-sea interaction and weather observation.
