通过SystemVue软件仿真平台调用C++代码动态链接库,建立了气象雷达脉冲调制器的仿真模型,给出了调制器回扫充电过程的仿真公式,研究了调制器关键点波形的产生和常见故障的仿真。仿真结果表明:该仿真模型能实现对调制器常见故障以及调制器回扫充电过程的仿真,输出符合要求的负极性调制脉冲。

By calling the C++ code dynamic link library through the SystemVue software simulation platform, the simulation model of weather radar pulse modulator is established, the simulation formula of the modulator flyback charging process is given, the generation of the modulator′s key point waveforms and the simulation of common faults are studied. The simulation results show that the simulation model can realize the simulation of the common faults of the modulator and the flyback charging process of the modulator,and output the negative modulation pulse that meets the requirements.
