How does a scatterometer work
WebFeb 23, 2000 · A scatterometer is a radar designed for measurement of ground or sea reflectivity. A brief description of a scatterometer application is given in this section for the measurement of wind speed at sea surface level from a satellite. Sea surface wind creates undulations that modify the backscatter coefficient. WebSASS (Seasat-A Scatterometer System): SASS (of S-193 heritage on Skylab) is a fan-beam dual-polarised Doppler scatterometer with the objective of radar backscatter measurements (sigma naught) over ocean surfaces for estimation of the wind field.
