摘　　要：在假单脉冲体制雷达的中频信号模拟中，由DSP配合软件实现的锥扫调制模拟，运算速度慢且数据传输量大。针对该问题，提出了一种基于LabVIEW语言和PCI-5640R中频卡的信号锥扫调制的实现方案，根据中频卡中的FPGA可编程实现多路并行运算的特点，利用LabVIEW对其编程，并进行仿真实验。结果表明：该方法模拟效果好，运算速度快，而且实现简单。In the fake single pulse system, simulating the intermediate frequency signal of radar, usually uses the DSP to carry out the simulation of the conical scan modulation,but its rate of operation is slow on some occasions. To solve the problem,the project based on the LabVIEW and the PCI-5640R intermediate frequency card is put forward. Using the characteristic that the FPGA can be programmed to calculate paratactically,and the simulation experiment is carried out. The result indicates that the method of simulation is good, the rate of the operation is high and the method is easy.
