| 摘 要： | 研究利用多组叠前地震记录剔除噪音对弹性波反问题求解的干扰．通过分析弹性汉反问题的误差曲面，得到了反问题解的置信域；将解的置信域以线性约束描述，可应用线性规划方法求得各个反演参数较窄的变化区间，从而提高了弹性波反演的分辨率．本方法适用于各种非线性反演．

| Abstract: | This paper studies how to reduce error caused by noise in elastic wavefield inversion with multi-prestack seismogram dataa. The confident domain of solutions of the inverse problem is achieved through analyzing misfit function of elastic wavefield inversion and more narrow confident limits are obtained by linearizing confident domain and solving with linear programming method, so the resolution of elastic wavefield inversion is improved. The method presented here can apply to various nonlinear inversions. |
