摘要
天气雷达在灾害性天气预警中发挥着至关重要的作用,近年来发展了多项天气雷达新技术。首先,概述了平面相控阵、曲面共形相控阵、稀疏阵、泛探雷达、无源探测、认知雷达等技术在天气雷达中的研究和应用;其次,介绍了新信号处理算法,包括波形设计、谱处理、副瓣白化等,特别是利用这些技术在天气雷达探测性能提升方面的研究;最后,介绍了采用最新天气雷达技术的大兴机场相控阵天气雷达。
Weather radar plays an important role in disastrous weather early warning.In recent years,a number of new weather radar technologies have been developed.Firstly,the research and application of plane phased array,curved conformal phased array,sparse array,ubiquitous radar,passive detection and cognitive radar in weather radar are summarized.Secondly,it introduces the new signal processing algorithms,including waveform design,spectrum processing,sidelobe whitening and so on,especially the research on improving the detection performance of weather radar by using these technologies.Finally,the Daxing airport phased array weather radar using the latest weather radar technology is introduced.
