Abstract

A microwave radiometer with two receivers, in which the sensitivity and stability of conversions are increased by using the zero method of measurement, is described. The operating principle is the synchronous use of two forms of pulse modulation – amplitude and width. The generation of signals which control the width modulation using a special algorithm for each receiver, improves the linearity of the radiometer transfer characteristic.
