| 摘 要： | 针对船舶地震波场传播路径复杂，不同路径信号叠加后难以区分的问题,提出了一种基于斜投影分离算子的信号分离方法。该方法利用波场极化特征差异，通过构建水中信号和表面波信号的极化子空间从而实现2种传播路径信号的分离。与传统的极化分析方法相比，该方法不需要通过变换和补偿就可实现信号的分离，且不影响信号的幅度/相位信息。对仿真数据和实测数据进行分析表明,斜投影分离方法是一种有效的波场分离方法。

| Abstract: | In view of the compltcated propagation path of the ship seismic wave field and the undistionguishable superimposed path signals, a ship seismic wave field separation method is introduced based on oblique projection separation operators by constructing the polarization subspaces of the compressed wave and surface wave respectively, thus separating the signal directly. Compared with the conventional polarization methods, no transform and compensation is needed to realize the signal seperation. The simulation and experiment data results indicate that the proposed method effectively separates the ship seismic wave field. |
