摘要
介绍求解目标散射特性的Mie理论和有限积分法,给出降水测量中RCS的具体表达形式,将球形雨滴RCS(雷达散射截面)的Mie理论计算结果和有限积分法计算结果进行比较。用基于有限积分法的CST软件计算了各种形状雨滴的RCS,与球形雨滴的RCS进行比较,求解出误差,提高了降水测量的精度。
The Mie theory and Finite Integration Method used to solve the object scattering property were introduced.The specific expression of RCS （Radar Cross Section）in precipitation measurement was given.RCS of the spherical raindrop solved by Mie theory was compared with which solved by Finite Integration Method.The RCS of random shape raindrops was solved by software CST used Finite Integration Method,which was compared with the RCS of spherical raindrop.The error is solved.The precision in precipitation measurement is improved.
