我国地基天气雷达技术系统发展介绍

Introduction to Development of Ground-Based Weather Radar in China

回顾了我国天气雷达从常规雷达发展到单极化多普勒,再到双极化多普勒,雷达获取目标的参数信息更加丰富的过程。分析了常规、单极化多普勒、双极化多普勒雷达工作原理及其产品信息。对于我国新一代S、C和X波段的天气雷达性能进行了研究对比。阐述了毫米波段多普勒测云雷达工作原理及其产品。对新一代天气雷达网进行了分析及展望,双极化将是我国天气雷达网升级改造趋势,为弥补新一代天气雷达探测盲区,小型移动电扫描雷达也是一种辅助主雷达网可移动灵活布网的趋势。

With the development of radar technology across the world, the domestic radar has developed from conventional radar to single polarization Doppler, then double polarization Doppler, with the target information obtained being more abundant. The principles and product information of conventional radar, single polarization Doppler, and double polarization Doppler radar are introduced in detail. The performances of the next generation S-, C-, and X-band radar are compared, which has a certain reference value for the selection of the radar wavelength. The millimeter-wave Doppler radar is also introduced, which can obtain cloud structure information. The performance and trends of the next generation radar network are evaluated. The double polarization Doppler radar will be the main trend; the electronicscanning small mobile radar will also become important for its flexibility, to make up the blind spots of next generation weather radar sounding.
