The optimal algorithm of radiometric imaging in chopper radiometric devices is synthesized and investigated. The highest accuracy of the estimation is reached due to zero type receiving which directly follows from the analysis of signal processing optimal algorithm. Such type of the receiver allows to obtain unbiased estimate of radio image (radio brightness as functions of angular coordinates). According to the algorithm the block diagram of a radiometer is developed, the potential accuracy of the image estimation and receiver potential fluctuation sensitivity are derived.
