Aim: Algorithms, methods and means of receiving radio signals that can significantly increase the time of the radar measurements between adjacent calibration intervals. The intermediate report contains the results of a statistical synthesis of a method for processing ultra-wideband signals that ensure a stable operation of the receiver for a long time (from several hours to several days). Based on the results of the analysis of the obtained method, a block diagram of a modulation radiometer with power division in adjacent modulation periods was developed and its simulation was carried out in the data flow mode with the maximum use of negative factors affecting the stability of radiometric measurements. Taking into account the overall limitations of the nanosatellite, the characteristics of horn-lens antennas were studied and the optimal shape was chosen, which was developed and used in the design of the onboard radiometric receiver.
