The principle of imaging observation of synthetic aperture microwave radiometer is expounded. Factors such as sensitivity, integral time, antenna beam width, target bright temperature, background noise temperature, system operating frequency and target equivalent cross section of integrated aperture microwave radiometer are analyzed. The relationship between the distance, the system of the target observation ability to verify the simulation to explore the inconsistency array channel error compensation method. The research results will contribute to the practical application of synthetic aperture radiometer.
