In order to successfully receive the low orbit remote sensing satellite data carrying the SAR payload with decimeter resolution, and verify the working state and performance of the satellite payload, this project developed a set of Ka/S dual band remote sensing satellite receiving and processing mobile station. Aiming at the key and difficulties of narrow beam high dynamic satellite tracking, multi-channel high-speed remote sensing data of satellite-to-ground transmission, this paper focuses on key technologies such as narrow beam high dynamic target satellite tracking, ultra fast and high-performance all digital demodulation, and high-precision dual mode adaptive blind equalization. It is verified that the technical path is correct and the measures are effective through experiments, which can provide technical reference for the subsequent development of related systems.
