Design and Implementation of a Multi-channel System Level Test Scheme for High Orbit High Power SAR Satellite

This paper introduces the design and implementation of multi-channel system level test scheme for high orbit high power SAR. Firstly, the working principle of high orbit SAR load is introduced, and then the composition and design scheme of SAR load comprehensive test equipment which is composed of echo simulator and SAR fast view are introduced. The test scheme design of satellite ground test link, test items and test methods for the characteristics of high orbit high power SAR satellite are carried out. The load system level test scheme and method of high orbit SAR have been applied in the test task. This paper introduces the application in practice.
