The Research And Realization Of Communication Interface Card In Test Bench For Radar Signal Processor

This Test Bench is a project for the system of Radar Signal Processor, which mainly acquires the digit signal and analog signal output by Radar Signal Processor and analogues and simulates all kinds of target signal and radar environment. It is an important equipment to test radar performance. In accordance with the importance of the communication interface card in the system, it has made a profound research in the design and realization process of it in this paper.In this paper, it introduced the design demand and principle, technical measures, constitution principle and operation mode. The communication interface card uses modularized design conception, its main function modules include: multi-logic-controller module, USB transmission module, McBSP serial communication module, high-speed data buffer module, bus and back board module. It analyzed the design principle and realization process of each module in this paper, and detailed described the data transfer protocol in the research process, its main protocols include: data load-up, error control during the communication process, data load-down. Reason of each communication protocol proposed, problem demanding dealing with and ways to implement were analyzed. Only in this way all these communication protocols were solved, the research of the whole system can be made smothly.The system has been ultilized and participated in many tests. Through these tests, it can be concluded that the system is accord with the requirement of the task and amount to the performance index.
