摘要
Abstract
The 5m S-SAR satellite is the first synthetic aperture radar(SAR)satellite in China to use a phased array feed source combined with an ellipsoidal parabolic system.In response to the new technological characteristics of the SAR payload and real-time processing payload on board,it is necessary to construct a integrated satellite-ground full-link semi-physical simulation and ver-ification system to simulate the working mode of satellite in orbit,to comprehensively test and verify payload performance indicators,subsystem interface compatibility,and environmental a-daptability.The paper proposes and constructs a semi physical simulation and verification system for the integrated satellite ground full link system.Ground equipment related to the payload is the core of the system and includes echo simulators,absorption boxes,and real-time ground data processing units.It enables closed-loop system testing of the satellite platform and payload throughout various test phases in the integrated satellite state,and realize automatic interpreta-tion and consistency checking of test data.After testing and verification,the results show that the system scheme is feasible,the testing method is reasonable and effective,and it can provide reference for testing other SAR satellite payloads.关键词
