透射波成像最大熵方法研究

MAXIMUM ENTROPY METHOD OF TRANSIT WAVES' TOMOGRAPHY

应用最大熵剑桥算法从透射波数据中挑选图像熵最大的模型作为反演结果,在算法中引进了一种新的约束条件,解决了某些情况下无法数值求解的问题。通过数值模拟及对清江某地区资料的处理,证明算法收敛性强,有较好的抗噪性。

The model with maximum entropy is selected as an inversed result by using maximum entropy combridge algorithm. The constraint condition is given in solving convergence problems under certain condition.The results from the computer numerical expriment and the process of the perspective data of electromagnetis waves in a certain area, show that the algorithm is effecttive to inderse incomplete wave filed data with noise and the image quality is largely improved.
