| Abstract: | We explore a quantitative correlation among X-SAR response and near-surface precipitation rain rate.Two simplified empirical inversion algorithms,regression empirical algorithm(REA) and modified regression empirical algorithm(MREA),based on statistical regression,are developed to retrieve near-surface precipitation rain rate.From the principle of precipitation inversion algorithm,the characteristics of MREA are investigated.A discussion of qualitative error estimation in the retrieval is presented. |
