| With the extensive application of the Beidou Satellites Navigation Positioning System in China, the Terrestrial test equipment for Satellite-Carrier Transponder has been Indispensable for the performance testing day after day. The Terrestrial test equipment is of great significance for the development and Implementation of the Transponder equipment.This thesis is based on a design of Terrestrial test equipment for Satellite-Carrier DS/FH Transponder. The primary task of the Terrestrial test equipment is to simulate the Dynamic characteristic of the Satellite signals, the interference signal and so on, and so that it can achieve a complete test for the transponder.At the first, the emphasis of this paper is based on 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-Carrier 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. And Then elaborates the design of the function modules of the simulation signal sources, including the design of software and hardware, such as the interference signal resources, the realization of high dynamic doppler in FPGA design and the combination of DS/FH in communication system.The results of the thesis indicate that the terrestrial test system achieved the design based on the technical indexes required by the Satellite-Carrier DS/FH Transponder. In cooperation with the space institutes to verify the terrestrial test system, it achieved the desired function, and got the actual effects. |
