Differences in RCS of Shaped Vs Spherical Raindrops Through Simulations

Abstract:

In this work we study the radar cross section (RCS) of a raindrop using electromagnetic simulation sofware. Particularly we compare the response of two models of singular raindrops: the first one is a real raindrop shape model proposed by Pruppacher and Pitter and the other is a spherical model that contain the same water volume and is used to extract the meteorological parameters from the RCS, assuming that the RCS is the same of the real raindrop. We make this study for several raindrop sizes and for the most common frequency bands used for weather radars. We analyse here the difference of the RCS for both shapes and so on, the errors that could be occur by the assumption made.
