基于矩方法的多视广义极化K-分布参数的估计

A Moment-based Paremeter Estimating Method for Multi-look Generalized K-distribution

本文提出通过归一化极化联合矩对ＳＡＲ多视广义极化Ｋ－分布参数进行估计的方法．本文深入阐述了ＳＡＲ各个极化通道之间的纹理相关性；在此基础上给出了多视广义极化Ｋ－分布波形因子，纹理相关系数和相干班相关系数的偏差性能分析；本文最后进行了蒙特卡洛实验论证，进一步证明了该方法的良好估计性能。

A moment method for estimating parameters of multi-look generalized K-distribution is prsented. We analized characteristics of partially correlated texture. The bias quality of every two polarized channels of SAR is also discussed. Finally, the Mont-calo simulation results show the method has a good estimating quality.
