Studies on the Use of Non-Conventional Imaging Methods with Narrow- and Wide-Angle Crustal Seismic Data

由美国国家科学基金会支持的IRIS/PASSCAL仪器项目提供了一种新的地壳探测技术，该技术使用了垂直入射和广角地震反射相结合的数据集。对于这类涉及密集的接收机部署和粗间隔射击的数据，没有令人满意的处理方案。这很可能成为标准的地壳勘探几何图形。这项研究将开发计算机技术来直接处理地震射孔集，而不是使用共同深度点（CDP）方法。这里开发的数据处理能力将对工业勘探工作有价值，并且是利用新的地壳成像技术所需的基本工具的一部分，这些技术将被许多科学调查所使用。

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.
