| Abstract: | 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] |
