摘要
NI公司以PXIe硬件系统为基础的LabVIEW FPGA模块可以达到严格实时性的要求,采用此系统可以实现雷达接收系统的硬件仿真。实验结合雷达数据传输过程严格的时间计算,重点介绍了LabVIEW FPGA模块FIFO的工作原理及其深度的设定方法,详细说明了LabVIEW FPGA的数据控制、传输过程,并采用特殊的数据源,仿真了雷达系统并检验了数据传输的过程,实验结果达到了预期目的,证实了实验方法的正确性。
LabVIEW-based FPGA module on the basis of PXle hardware system produced by NI company meets the real- time requirements and realizes hardware simulation of the radar signal receiving system. Combined with time calculation in ra- dar data transmission process, the paper put more emphasis on the working principles of LabView-based FPGA module FIFO and the method for setting its depth, and described data control and transmission of LabVIEW-based FPGA in detail. Special data source was adopted to simulate radar system and test the data transmission process. The experimental results achieved desired objectives and confirmed the correctness of the experimental method.
