Abstract


TT&C Technology (Tracking, Telemetry and Command Technology) is one ofthe most important of aerospace technology. Compared to the launching technology,receiving technology has been in catch-up phase. With the rapid growth of emissiontechnology, the receiving system must correspond to the direction of high-speedbroadband digital processing. There are a lot of aerospace monitoring systems in theworld. A receiver will be suitable for unattended operation if it adapts to different TT&C models and tasks in different frequency ranges.The structure of conventional analog receivers or the conventional digital receiveris changeless and running a single mode. Nowadays researchers have joined the studyof the all-digital receiver based on Software Defined Radio. And correspondingreceiving technology have emerged as the time requires. The best way to implement afully digital receiver is to conduct a digital processing of RF sampling directly at theback-end of antenna. So this paper builds up a high speed down-conversion filteringstructure to research and implement broadband receiver technology in the aerospacemonitoring system.This paper in-deep studied the principles and composition of the receiver systembased on broadband receiver and high-speed digital processing technology, and built upan overall framework of the broadband receiver to meet the demand of this project.Then, this paper researched and designed the down-conversion filtering technology athigh-speed and synchronization technology according to the system design. And themultiphase conversion&multiphase filter structure can run in the FPGA digital deviceswas set up to realize RF samples directly from the radio-frequency signal, which wassuccessfully tested under MATLAB. We have analyzed the common Synchronizationtechnology and combined with the project need to choose the appropriatesynchronization method. Then Simulation and test it in MATLAB. Finally, according tothe needs of the project, the A/D and FPGA development board has been selected. Andthrough Verilog HDL programming language, the receiver is implemented in thehardware structure. This paper highlighted NCO, CIC, HB module design, and analyze its performance. The test results of the receiver on hardware structure showed that thegood performance of the receiver, which meant broadband receiver design succeed.
