How does a scatterometer work
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. WebScatterometer Overview →. Measurements. Measurements can be used as a measure of quality for optical surface finishes and films, as a way to characterize point defects and …
