Abstract :
A microwave radiometer designed for remote sensing infers geophysical information from the thermal emission from natural targets. The most useful frequencies span 6 GHz to 37 GHz, and incorporate a scanning antenna to provide radiometric maps of the Earth surface and the atmospheric burden. This paper focuses on radiometric imaging systems, and the observational value offered by these systems since they were first flown on spacecraft nearly 30 years ago.
