Performance of the wet radomes for phased-array weather radars: Evaluation and applications

The concept for an analytical method for evaluating the electrical performance of a flat, tilted radome for a dual-polarized phased-array antenna under rain conditions was de-voloped. Attenuation, reflections and induced cross-polarization are evaluated for different rainfall conditions, taking into account the properties of the skin surface, area, inclination, radome structure, and rainfall rate. In order to illustrate the utility of the new wet radome model, this paper evaluates four different scenarios which provides a better understanding of the model proposed.
