Instrumental errors of radiometric aperture synthesis systems are analyzed. The errors caused by the quantization of input data and by rounding off intermediate results are shown to be energy errors in nature, and their effect is limited to some increase in the image background noise. Dissimilarity of channels of preliminary signal processing and errors in the antenna array geometry produce the same effects. Relations which describe the requirements imposed on radiometric system components have been derived.
