摘　　要：1灾害天气监测1.1观测模式固态发射机体制的Ka波段云雷达回波强度谱密度质量控制、融合和再分析方法为了满足云雷达稳定连续观测的需求,中国气象科学研究院与中国航天科工集团23所联合研发了多观测模式固态发射机体制的Ka波段云雷达,该雷达采用了3种不同脉冲宽度、不同相关和非相关积累的工作模式,以实现近距离弱降水和远距离弱云的观测,并用于华南云降水观测。1 Severe weather monitoring technology 1.1 Algorithms of Doppler spectral density data quality control and merging for the Ka-band solidstate transmitter cloud radar The Chinese Ka-band solid-state transmitter cloud radar (CR) can operate in three different working modes with different pulse widths and coherent integration and non-coherent integration numbers to meet the requirement for long-term cloud measurements. The CR was used to observe cloud and precipitation in Southern China in 2016. This study focuses on analyzing the consistencies of reflectivity spectra using the three modes and the effect of coherent integration and pulse compression.
