摘　　要：为了使固态天气雷达同时具有较强的探测威力和较高的距离分辨力,需引入脉冲压缩技术。介绍了线性调频信号的脉冲压缩技术,结合理论仿真结果,选用合适的加权网络并在全固态天气雷达中进行了工程实现。最后利用探测的天气回波强度信息对脉冲压缩技术的理论进行仿真验证,得到了与理论研究一致的结论。In order to make the solid-state weather radar has the strong detective power and the high range resolution at the same time, the pulse compression technique is necessary to be used. First of all, this article introduces the principle of pulse com- pression technique. After that, based on the simulation result, the paper presents the system implementation of projects, including hardware and software. Finally, the simulation is verified by detecting weather echo using solid-state weather radar. The experimen- tal results are close to the theoretical result obtained before.
