Abstract :
The principle of time division in multi-receiving radiometric systems of the null method of measurements with the composite impulse modulation, allowing increasing fluctuation sensitivity of systems, is described for the case when long term and temperature stability, as well as dynamic properties, are kept. The diagram of the two-channel radiometer and the description of a principle of time division for the multichannel diagram are presented.
