Abstract:

L-band wind profile is used in coherent accumulation technology to rise radar sounding sensitivity, vertical measurement precipitation cloud body is applied,which can obtain the entire spectrum information of cloud body return signal of high resolution.The wind profiler is used to continuously detect the bright band appeared in stratiform cloud precipitation process on May 14,2009.The variation and evolution characteristics of return signal spectrum parameter(power,average Doppler velocity,speed spectral wi...
