Abstract

The invention provides a space-based radar efficiency optimization method. The method includes the following steps: determining an inclination angle of a track on the basis of a latitude zone of a target area and the loading distance of space-based radar; calculating the height of the track according to the loading distance of space-based radar and the inclination angle of the track; and arranging multiple space-based radar satellites on the same track surface by enabling the phase angles of the satellites to be equal or arranging the space-based radar satellites on N track surfaces. A zero-degree inclination angle of a non-zero-degree inclination angle of a track can be selected on the basis of a latitude zone of a target area and the loading distance of space-based radar, that is to say, a track with a low inclination angle can be selected. Therefore, the target area can be detected many times and the high system efficiency can be achieved by means of relatively less satellites, and a high temporal resolution detection requirement of an airplane target can be met.

Description

technical field [0001] The invention relates to the overall design of satellites, in particular to a space-based radar performance optimization method. Background technique [0002] Space-based radar is an active detection method. It has the advantages of high radar station, large coverage, high positioning accuracy, and downward-looking detection is conducive to anti-stealth. It fills the gap in space-based aircraft detection methods. [0003] Considering that aircraft and other targets are moving targets, with the characteristics of fast movement and strong maneuverability, space-based radar needs to have high system efficiency, that is, to use as few satellites as possible to achieve high time-resolution reconfiguration of the area of ​​interest. visits, thereby ensuring continuous detection of aircraft targets. [0004] After searching the existing technology, it is found that the application number is 201210000464.3, and the name of the invention is the space multi-tar...
