| 摘 要： | 阐述了常规线性Radon变换和时间域高分辨率线性Radon变换的基本原理,讨论了Radon变换的端点效应、截断效应和空间假频问题,同时给出了利用相似函数法压制端点效应的方法和避免空间假频的参数选择原则,并且对理论模型用文中提到的方法进行波场分离并进行了误差分析,取得了较好的效果,表明时间域高分辨率线性Radon变换能够使线性同相轴的能量得到较好的收敛,对波形的恢复较好,取得了良好的上下行波分离的效果。

| Abstract: | This paper expatiated normal linear Radon transformation,high resolution Radon transformation,and discussed the endpoint effect,truncation effect,and spatial aliasing in Radon transformation.Otherwise,this paper gave a solution to the endpoint effect and the principle of choosing parameter to avoid spatial aliasing.It also made an error analysis based on above model,and the results proved that the method got a well effect. |
