[Abstract]:With the rapid development of science and technology, the amount of data produced and processed in the application process of radar, communication and space vehicle is increasing explosively. The requirements for the rate, reliability, stability and storage capacity of the data transmission system are getting higher and higher. The traditional parallel data transmission system is becoming more and more difficult to meet. Modern equipment has high bandwidth, high reliability and long distance transmission requirements for data transmission. Therefore, the study of the new data transmission system is not only of theoretical significance but also more practical. This project comes from a continuous wave radar project. This project requires that the data transmission system has long transmission distance, large bandwidth, low delay and reliable data transmission system. On the basis of full investigation and analysis of the existing data transmission technology and system, a high-speed data transmission system based on FPGA and optical fiber technology is designed and implemented. This system is composed of data transmitter and data receiver, which can achieve long distance, large bandwidth and low between the two. The specific research work of this paper is as follows: firstly, through extensive research on current mainstream data transmission technology, the real-time transmission technology suitable for radar echo data is selected. Two, the application background of high speed data transmission system in a CW radar is introduced, and the key technologies related to this topic are also introduced. Research, including data frame technology, data verification technology and synchronization design technology, and so on. Three, the overall framework design of the system is completed by analyzing the functional requirements and requirements of the data transmission system. Four, the programming implementation of FPGA related functions and interfaces in this transmission system is studied in detail, including the Aurora string. The line transmission module, the DDR3 SDRAM interface and the PCI Express bus interface, etc.. Five, in order to verify the function and performance of the system, the designed data transmission system is tested in detail. It includes the real-time processing of the data transmitted through the upper computer, the debugging of ISE ChipScope software and so on, which verifies the correctness of the system function. It shows that the data transmission system designed in this paper has the characteristics of large bandwidth, large capacity and high stability, and the data transmission rate can reach 150MB/s, which can meet the data transmission requirements of the CW radar.
