Overall control method of large-angle maneuvering high-resolution microwave remote sensing satellite

Abstract

The invention provides an overall control method of a large-angle maneuvering high-resolution microwave remote sensing satellite, comprising the following steps: S1, systematically identifying the difference between a large-angle maneuvering high-resolution microwave remote sensing satellite and other existing satellites at the technical level, and determining key problems to be solved; S2, determining a scheme of maneuvering around the rolling shaft of the satellite according to the specific requirements of large-angle maneuvering; and S3, in view of the fact that the detection range of sensors fixedly connected to the satellite changes with maneuvering of the satellite due to large-angle maneuvering, inventing a sensor field analysis method based on a space digital ball method to determine the layout of the sensors on the satellite. The high-resolution microwave remote sensing satellite has the ability to revisit a to-earth observation target. The technical difficulty in large-angle quick maneuvering of the attitude of the satellite is solved. The problem on multi-system integrated control is solved. The use efficiency of the satellite is improved. The problem of electromagnetic compatibility and the problem of wireless high-power transmission during whole-satellite vacuum thermal test are solved.

Description

technical field [0001] The invention relates to the overall technical field of satellites, in particular to an overall control method for large-angle mobile high-resolution microwave remote sensing satellites. Background technique [0002] Microwave remote sensing satellite is an active earth observation system. The radar installed on the satellite platform continuously transmits pulse signals, receives their echo signals on the ground, and synthesizes radar images after Doppler frequency shift. Microwave remote sensing satellites are not limited by factors such as weather, geography, and time. They can observe the earth all day and all day long, and can find hidden underground targets through vegetation, providing rich land and ocean geographic information and military intelligence. Resolution microwave remote sensing satellites can obtain high-resolution radar images similar to optical photography under weather conditions with extremely poor visibility. This makes microwa...
