摘要
该文通过对晴空大气返回信号特性的分析 ,提出采用相干累积技术 ,有可能提高多普勒天气雷达探测晴空大气的能力 ,具体测算了提高探测能力的限度 ,并对雷达信号处理器适应晴空探测进行了改进设计 .
By analyzing the characteristics of echo signal in the clear air, a coherent integral method is presented, which can improve the probing ability of Doppler weather radar in the clear air, and the limit of the improved ability is calculated. Based on the study, the design of the radar signal processor is improved to be applicable to the detection in the clear air.[WT5BZ] [WT5HZ]
