| With the extensive application of the Beidou Satellites Navigation Positioning System, the Terrestrial test equipment for Satellite-Born Transponder has been Indispensable day after day. The Terrestrial test equipment is of great significance for the development and Implementation of the Transponder equipment.This thesis gives out a design of Terrestrial test equipment for Satellite-Born DS/FH Transponder. The primary task of the Terrestrial test equipment is to simulate the Dynamic characteristic of the Satellite signal, the interference signal and the user equipment, and to do a complete test of the transponder.The emphasis of this paper is to give out the overall design and subsystem design of the terrestrial test equipment. This subject analysis the design requirements and the basic principles of terrestrial test equipment for Satellite-Born DS/FH Transponder, and finish the related software and hardware design by using of the IPC with the FPGA architecture and the main interface of PCI. Ultimately, the terrestrial test equipment can simulate the transmission signal and the reception signal of the satellite communication device, finish the test and get the test function parameters.The results of the thesis indicate that the terrestrial test system achieved the design above. In cooperation with the space institutes to verify the terrestrial test system, it achieved the desired function, and got the actual effect. |
