The new IRIS/PASSCAL instrumentation program supported by NSF has made available a new crustal exploration technique using data sets which combine vertical-incidence and wide-angle seismic reflections. No satisfactory processing schemes exist for this type of data which involve denser receiver deployments with coarsely spaced shots. This will likely become the standard crustal exploration geometry. This research will develop computer techniques to directly process seismic shot gathers, rather than working with the Common Depth Point (CDP) approach. The data processing capabilities developed here will be valuable to industrial exploration efforts and are part of the essential tools needed to take advantage of the new crustal imaging techniques that will be used by numerous scientific investigations.

由NSF支持的IRIS/PASSCAL新仪器计划提供了一种利用垂直入射和广角地震反射相结合的数据集进行地壳勘探的新技术。对于这种类型的数据，不存在令人满意的处理方案，其涉及具有粗略间隔的激发的更密集的接收器部署。这可能会成为标准的地壳勘探几何图形。这项研究将开发直接处理地震炮集的计算机技术，而不是使用公共深度点(CDP)方法。这里开发的数据处理能力将对工业勘探工作很有价值，是利用许多科学调查将使用的新地壳成像技术所需的基本工具的一部分。
