Abstract: The microwave responder is one of the important cooperative targets for spacecraft rendezvous and docking. To insure that the equipment has a good performance inorbit, a special simulator is needed in the spacecraft test before it is sent to orbit. A design of the simulator is introduced in this paper, and the corresponding function and performance requirments are analyzed. Based on the modularized design, a hardware and software design method is provided in this paper. Finally, the operating process and the test performance of the designed simulator are introduced.

Key words: microwave responder, simulator, modularized design
