USB2．0技术在雷达目标识别系统中的应用

在雷达目标识别系统算法测试过程中,需要对大量的原始数据进行分析从而得出识别结果然后进行算法优化。由于雷达回波数据量大,因此需要采用高速的传输方式将试验数据传送给目标识别单元,这样才能最大限度地模拟真实环境,达到系统需求的数据率24Mb/s,满足目标识别的实时性要求。利用CY7C68013A和TMS320VC5402实现USB2.0技术,将先期试验数据送到目标识别单元,数据传输速度可以达到40Mb/s,满足了目标识别的实时性要求,并且可以将识别结果传回PC以便进一步分析。

Application of USB2.0 in the radar target identification system

In the test of algorithm for radar target identification system,we need to analyze a great number of original data to get the identification result,and then improve the algorithm.As the mass radar echo data,a high-speed transmission method should be taken to transmit the previous experimental data to the unit of radar target identification for test,only in this way it can maximally simulate the virtual reality environment and meet the real-time request and the data rata of 24 Mb/s.Using CY7C68013A and TMS320VC5402,it can realize the USB2.0,and transmit the previous experimental data to the unit of radar target identification.The transmission speed can reach 40 Mb/s,so the USB can satisfy the real-time request of radar target identification and transmit the results to PC for further analysis.
