| 摘 要： | 针对毫米波测云雷达受云雨衰减的问题,从雷达I、Q信号角度出发,模拟毫米波测云雷达回波I、Q信号并假设一定的探测环境,进行雷达回波信号衰减补偿仿真试验.试验结果表明,雷达电磁波信号穿过雨区和云区时,在远距离处衰减量很大,通过衰减补偿,信号强度明显增强,目标信号突出.

| Abstract: | According to the attenuation problem of Millimeter wave cloud radar from cloud and rain,this article is from the perspective of the I／Q signals,and simulates radar echo I／Q data,at the same time,assumes a certain detection environment,carries out radar echo signal attenuation compensation simulation experiment.The results show that radar electromagnetic wave signal through rain area and cloud area,attenuation is large in a remote place.Signal strength and target signal is obvious enhanced by attenuation compensation. |
