Stochastic analysis of modulation microwave radiometers with square - law and linear detectors is presented in the paper. Assuming ideal detector characteristics it is shown that in typical applications, i.e., in very low power measurements, a type of detector used is of no influence on total radiometer sensitivity. Other aspects of use of a particular detector are also presented.
