More Information
Summary:Classical scheme of correlation radiometer includes two identical high frequency transformation channels with outlets switched to a multiplier. Availability of two transformation channels considerably complicates the task of engineering implementation of the given radiometer, the more so in SHF range. On the basis of commutation-modulation transformation, the authors have designed a one-channel radiometer scheme which is much more easily realised. The simplified scheme of modulation-correlation radiometer which measures random signal power and also permits one to register the autocorrelation function is given.
