instrument, mida kasutatakse meteoroloogilistel satelliitidel merepinnalt hajunud valguse mõõtmiseks
scientific instrument to measure the return of a beam of light or radar waves scattered by diffusion in a medium such as air

Radar scattometers use radio or microwaves to determine the normalized radar cross section (sigma-0) of a surface. They are often mounted on weather satellites to find wind speed and direction, and in industries to analyze surface roughness of surfaces. Reference: 'Scatterometer'.

'The scatterometer is another active microwave instrument that can be used to study sea state. Unlike the altimeter, which uses a single beam directed vertically downward from the spacecraft, the scatterometer uses a more complicated arrangement that involves a number of radar beams that enable the direction as well as the speed of the wind to be determined.'
