The Quick Formulas for the common radar wave bands of S, C, X and Ka have been obtained. It has been shown that the accuracy of Quick Formulas is more than 95%, that is, the error is less than 5%, and the time consumed is negligible as compared with DDA computation. The resulting codes can be inserted into the software for radar reflectivity simulation and real-time attenuation correction of rainfall estimation with radar. 收起
