A New Principle for Construction of Microwave Multireceiver Radiometers Using a Modified Method of Zero Measurement

详细

We consider a microwave multireceiver radiometer based on in-parallel operated receiving channels using the principle of zero balance and measuring the antenna signal by all receivers in the same spectral range with time division. This yields a higher fluctuation sensitivity than in the case of an ideal full-power compensation radiometer while achieving a high stability of measurements by a modified method of zero measurement.
