摘　　要：根据第一代天气雷达发射机在全国各地布网的百余套长期运行过程中暴露出来的技术和维修方面的问题,结合近年来先进电路设计思想和器件应用方法,研制了新一代天气雷达发射机。文中从调制器高压充放电电路模块化设计,新型功率器件在电路中的具体应用,几种特殊形式数据采集电路的分析比较,多种工程实用化的技术优化改进等方面进行了详细的论述,给出具体的应用电路和实物照片,并总结了批量生产发射机设备的设计原则。According to the technology and maintenance problems exposed on the first generation weather radar transmitter, which are operated in long period across our country, combined with the advanced circuit design principle as well as the device application, the new generation weather radar transmitter is designed. The modular design of high voltage charging and discharging circuit of the modulator, the application of the novel power devices in the particular circuits, the comparison and analysis of several specific data acquisition circuits, the optimization and improvement of several engineering technology are proposed particularly in this paper. The description are also given followed with the specific circuits and photos. The design principle of the transmitter equipment in batch is summarized lastly.
