一种雷达回波采集及显示方案设计

Design on Radar Echo Acquisition and Display Scheme

针对一种雷达回波采集及显示方案,通过数字接收机对雷达回波信号进行数据采集并通过数字下变频将其转换为IQ数据,利用光吉比特以太网实现将IQ数据传输至计算机,以LabVIEW为IQ数据接收及显示开发工具,最后通过实际测量验证了设计可实现回波采集及回波显示功能。结果表明设计在减少硬件成本的同时,可降低软件开发周期,具有较强的实际应用价值。

In order to design a radar echo acquisition and display scheme,the radar echo signal is collected by digital receiver and converted into IQ data by digital down-conversion. The IQ data transmission is realized to the computer by using optical Gigabit Ethernet. LabVIEW is used as the IQ data receiving and display development tool. The actual measurement demonstrates that the design can implement the functions of echo acquisition and echo display. The results show that this design can greatly reduce the software development cycle while reducing the hardware cost,and it has higher practical application value.
