相控阵天气雷达技术研究进展

Advances in Phased Array Weather Radar Technology Research

摘要: 天气雷达是一种典型的气象雷达，也称测雨雷达，是用于警戒和预报中、小尺度降雨天气系统的主要探测工具。自第一部天气雷达问世以来，社会经济的持续发展和科学技术的进步，推动了天气雷达技术不断创新发展，经历了常规模拟、数字化、多普勒、多普勒双偏振等发展阶段。天气雷达的核心部件发射机系统也从磁控管、速调管发展到全固态、相控阵技术。本文介绍国内外相控阵天气雷达技术研究进展，重点综述相控阵天气雷达技术研究进展。内容包括：介绍气象微波波段与天气雷达种类，介绍天气雷达体制发展进程，介绍双线偏振多普勒天气雷达；综述相控阵天气雷达技术进展，以及介绍几种新发展的相控阵天气雷达等。最后，给出总结和展望。

Abstract: Weather radar is a typical meteorological radar, which is also called rain radar. It, as the detection tool, generally provides service for warning and forecasting on the small and medium scale rainfall weather system. From the first weather radar, it has witnessed the continuous progress of weather radar technology, due to the continuous development of social economy and the progress of science and technology. Historically, the weather radar has developed from common simulation, digitaliza-tion, Doppler to Doppler dual polarization. The transmitter system, the core component of weather radar, has developed from magnetron and klystron to all-solid and phased array technology. This paper reviews both domestic and international advances in weather radar technology research. The meteorological microwave band, weather radar type, weather radar system, dual linear polarization Doppler weather radar and phased array weather radar are comprehensively introduced. Finally, a conclusion and outlook are provided.
