Comparison of dicke and ratio type modulation radiometers statistical characteristics of signal parameter estimates and fluctuation sensitivities

Algorithm of radio thermal signal processing in the radiometer, which is characterized by unstable gain in predetection section of receiver, is given. This algorithm compares with signal processing algorithm in Dicke radiometer. Differences in the signal processing are indicated and the statistical characteristics of the radio-brightness temperatures estimations are compared, and the fluctuation sensitivity of the receivers. The conditions are grounded with which the application of the new type modulation radiometer is the most expedient.
