雷达发射机是发射大功率高频电磁波的设备。对其进行测量往往需要高端昂贵的测量仪器，并且如果防护不当，微波辐射会对人体造成伤害。因此，在进行雷达发射机培训、演示过程中，常常是停留在关机状态下进行发射机组成的介绍，而对其各部分的信号往往得不到充分的展示和观察，使受训对象很难形成直观的感性认识，不易把握雷达发射机的工作原理。为了解决这个问题，本文基于 LabVIEW 软件开发了雷达发射机的仿真软件，采用模块化的设计，数字信号处理的方法实现方式，实时显示雷达发射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，雷达发射机的重要知识点均得到充分体现。

The radar transmitter has the characters as following:high frequency, high power, and the microwaves are harmful to human. So the training and demonstration of radar transmitter is often taken in the condition of shut off, the signal can’t be shown, the trainer can’t get the intuitionistic know and is difficult to understand the working principle. To solve this problem, the radar transmitter simulation software based on LabVIEW is developed in this paper, with the modular design and each module is realized by digital signal processing, and the signal wave and frequency spectrum of each module are real-time shown. The modules are divided clearly, the function is realized by explicit principles, and it is easy to be caught by the trainers.
