Retrieval of reflectivity in a networked radar environment

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
