Microwave Radiation Parameters Estimation Algorithm for Satellite Modulation Radiometer

The problem of algorithm synthesis for signal processing in a radiometer, which contains amplifiers input stages with an unstable gain, has solved. Marginal errors in the estimates of the observation equation parameters at the initial stage of their processing are calculated. On the obtained algorithm basis, a structural scheme of a chopper radiometer has proposed. The results of the circuit operation modeling that implements the synthesized signal processing algorithm have presented.
