Abstract：In view of the question of whether the performance of the high-sensitivity receiver put into mass production is guaranteed, according to the telemetry parameter characteristics of the high-sensitivity receiver, the channel AGC and SNR parameters sensitive to the environmental characteristics are analyzed, and using the test data under different conditions obtained by the test specified in the environment test specification, the performance consistency of the receiving channel is analyzed. The analysis of on-orbit data and ground environment test data shows that the channel performance of receiver in the two different environments is consistent, and the channel performance of the high-sensitivity receiver is stable, which ensures the broad adaptability of the de-mission product.
