摘要
雷达接收机比较复杂,其信号频率高,器件精密昂贵,对其进行测试所需仪器也造价不菲,因此在教学中往往很难进行实物的充分展示,另外由于其信号具有抽象性,在学生学习的过程中常常感觉很难掌握相关原理及组成结构。为了解决这个问题,论文基于LabVIEW软件开发了雷达接收机的仿真软件,采用模块化的设计,以及数字信号处理的方法实现,实时显示雷达接收机各部分的信号波形和频谱。模块划分清晰、功能实现原理明确、便于受训对象理解掌握,雷达接收机的重要知识点均得到充分体现。
The radar receiver is complicit and expensive,which frequency is high.And the test instruments are costly.So it is difficult to show in practicality.In addition,the signal is invisible,so many students feel that it is difficult to understand the principles.To solve the problem,the radar receiver simulation software based LabVIEW is developed,which is designed in modularization and DSP.And the signal wave and frequency spectrum are displayed in real-time.Modules are divided clearly,the principles of realization is definite,so it is easy to be caught by students.The key knowledge points of radar receiver are exhibited.
