The high-speed real-time acquisition and playback of radar data and the docking of the main control computer to complete the high-speed transmission of massive data, on the one hand, ensure the high-speed data acquisition and data analysis, On the other hand, to ensure the high-speed injection of playback data into the playback equipment to achieve algorithm verification, so as to carry out the radar target echo signal characteristics research, The research of radar dynamic performance test and new algorithm of radar signal processing provides an effective tool and means, at the same time, the interconnection of data acquisition equipment and computer through USB3.0 interface greatly enhances the data analysis ability of data acquisition and playback equipment. Because of the generality of USB3.0 interface, the adaptability of data acquisition and playback equipment is stronger. In this paper, the realization idea and structure of high-speed mass data transmission for radar data acquisition system are studied, and the assumption of high-speed data transmission in USB3.0 interface is put forward, and the principle and technical approach of the problems that need to be solved are studied. The USB3.0 interface Device controller is implemented with VHDL program, and the high speed transmission based on USB3.0 is realized. The transmission interface can be used in the radar test system to realize the real-time transmission of the high speed ADC data stream collected from the front end of the radar. With the powerful processing and analysis performance of PC, the echo data can be processed and simulated. The key problems of USB3.0 interface control, radar high-speed data transmission and storage are solved in this paper. It is verified by experiments that the maximum transmission rate of collected data can reach 300MBytes / s, which can meet the needs of most high-resolution radar test data transmission.
