广义脉冲谱方法的一个新形式及其应用
|
摘要
构造了一种新的、有一定抗噪能力的广义脉冲谱方法（ＧＰＳＴ）的计算格式。设计了选取正则参数过程中节省计算量的技巧．最后探讨了方法在地震勘探一维波方程反问题上的应用，进行了数值模拟。
This paper presents a new version of the generalized pulse-spectrum technique,which is popularly used for solving the inverse problem of differential equations. This version has the property of immunizing noises. The skill of aving computing time is also given in the process of choosing regularign parameters. In the end, the application on the inverse problem is seismic prospection is discussed, the numerical result of simulation is given.
