Application of System-Level EMC Design Technology in Microwave Remote Sensing Satellite

Characterized by wide frequency coverage, high power transmission and high sensitivity reception for the microwave remote sensing satellite, ninety-seven percent of the satellite devices cannot satisfy their standards or requirements in the receiving frequency band of payload, and the electromagnetic environment of the satellite is complicated. This paper mainly discusses the system level EMC design technology, including inhibiting the interference path, controlling the unexpected radiation emission of satellite products, and improving the shielding performance of cabin plates, to solve the interference problem, leading to a good electromagnetic compatibility for the satellite.
