| 摘 要： | 通过水中高分辨率超声波地震模型的采集与激发方式实验，研究了不同激发、采集方式对资料获取、信号质量以及反演结果等方面的影响。实验中进行了激发震源实验，激发震源采用的是阶跃脉冲和窄方波脉冲，结果表明前者所获资料的分辨率较高；进行了3种采集方式的讨论；分析了水平面的半无限空间对子的影响。

| Abstract: | In this paper we studied in a lab the effects of different shooting and receiving geometries on data acquisition, data quality as well as inversion results via a series of physical experiments on high resolution supersonic seismic models in a water pool. Shooting experiments on step pulse and burst square pulse show that the data generated by the former has higher resolution. Three receiving geometries used in the experiments and the effects of horizontal half space on wavelets are discussed. |
