本文介绍了一种方法，在网络化雷达环境中的反射率和衰减反演。从公共体积反向散射的电磁波沿着不同的路径被不同地衰减。通过求解反射率的积分方程，以类似于微分相位约束的方式，提出了特定衰减分布的解决方案。一组控制积分方程描述的后向散射和传播的共同分辨率体积的同时解决所观察到的总路径衰减的约束。开发的算法进行评估模拟X波段雷达观测在雨中获得的S波段测量CSU-CHILL雷达。用迭代法反演的反射率和比衰减与本征反射率和比衰减吻合较好
This paper describes a methodology for reflectivity and attenuation retrieval in a networked radar environment. Electromagnetic waves backscattered from a common volume are attenuated differently along the different paths. Solution of the specific attenuation distribution is proposed by solving the integral equation for reflectivity, in a manner similar to that used with a differential phase constraint. The set of governing integral equations describing the backscatter and propagation of common resolution volume are solved simultaneously with constraints on observed total path attenuation. The algorithms developed are evaluated on simulated X-band radar observations in rain obtained from S-band measurements by CSU-CHILL radar. Retrieved reflectivity and specific attenuation using the iterative method show good agreement with intrinsic reflectivity and specific attenuation
