中国不同地区降雨中光强衰减与方差特性研究
Research on light intensity attenuation and variance characteristics in rain of different regions in China
摘要
Abstract
This paper conducts a study of the relationship between the received laser intensity and the rain precipitations.First the MIE model is used to calculate the relationship between particle sizes and scatter parameters.Then the received laser attenuation including both coherent field and non-coherent field is calculated.In those calculation results,Marshall-Palmer distribution is com-pared with Drop Size Distributions of different regions in China.And the spectrum of scatter light is derived with the velocity of raindrops.It is found that as precipitation increases,the variance increases first,and then decreases.And it also relates to the attenuation.The model is verified by using measured data,with results indicating that the Marshall-Palmer distribution fits these data.关键词
