摘要
本文对Laws-Parsons和广州雨滴尺寸分布雨衰减(A)和降雨率(R)之间的指数关系(A=αRb)中的α和b值[1][2]进行了分析和解析回归,给出了其与频率的解析近似关系,利用其计算的雨衰减和数值计算结果有很好的一致性。
Based on a and b values[1][2] in the power law relations (A=aRb) of rain attenuation (A) and rainfall rate (R) for Laws-Parson. rain drop size distribution(L-P DSD) and Guangzhou rain drop size distribution (Guangzhou DSD)model, the analytic approximations of rain attenuation have been regressed and presented at frequencies 8-400GHz for L-P DSD and 6-400GHz for Guangzhou DSD. The errors between the analytic approximation and numerical results are ies than 24% 12%for L-P and Guangzhou DSD respectively in 1-150 mm/h rainfall rate.
