| Abstract: | This paper solved PSWF through the method of solving eigenvalue problem of integral equation. Then extrapolated it by use of PSWF, and finally reconstructed the graph which once was incomplete data caused by lack of angle. It's successful to avoid the ill posed problem. The result shows the algorithm built by the author, when more angle was lack, has gotten a satisfied result on effectiveness, accuracy ,stability and so on. |
