Mie versus Point Matching Algorithm for Radar Rain Properties Retrieval

This contribution compares retrieval algorithms after Mie (quick, but neglecting the real shape of rain drops) and after Oguchi (slower, but more exact) for radar forward scattering and backscatter at frequencies of 10 and 35 GHz. The retrieved quantities were drop size distribution (DSD), rain rate and attenuation (e.g. of microwave link). Measurements of drop size distributions over one year in the Czech Republic served as reference. The simulation shows that the simple Mie algorithm can be used on a good accuracy level.
