Abstract

The invention discloses a space-based radar system for multi-satellite ultra-short-distance follow-up flight. , large data volume transmission system; the satellite body is composed of satellite structure, attitude control, thermal control, power supply, and other sub-systems, which provide guarantee conditions for the work of the radar antenna. In the present invention, by launching a plurality of small-area radar antenna satellites, an ultra-short-distance follow-up flight is formed on orbit to ensure the distance and flatness between the antennas.

Description

technical field [0001] The invention relates to a radar system, in particular to a space-based radar system for multi-satellite ultra-short-range follow-up flight. Background technique [0002] In order to realize the detection of small and medium-sized moving targets, according to the radar equation, space-based radar needs an antenna with an area of ​​hundreds or even thousands of square meters, the antenna azimuth size is hundreds of meters, and the required power is as high as tens to hundreds of kilowatts. Considering Limited by the constraints of the carrying envelope and weight, it is difficult to achieve a single satellite; therefore, a space-based radar system for multi-satellite ultra-close follow-up flight is proposed. [0003] By launching multiple small-area radar antenna satellites, an ultra-close follow-up flight is formed on the orbit to ensure the distance and flatness between the antennas, which is equivalent to hundreds or thousands of square meters of rad...
