诸如共反射点方法等地震技术的多次地面复盖提供了多种波传播路径信息，这使得能够直接确定与这些路径相关联的均方根速度。对适当收集的轨迹阵列之间的相似性进行双曲线搜索形成了估计速度的基础。测量到的相似性以速度谱显示的形式呈现。对这一信息的解释可以给出初级和多重事件有意义的准确性的速度。此外，速度数据还可以帮助正确标记事件。本文概述了计算速度谱显示的基本原理。文中举例说明了可从这种显示的解释中获得的地质信息的深度和细节。
Multifold ground coverage by seismic techniques such as the common reflection point method provides a multiplicity of wave travel path information which allows direct determination of root‐mean‐square velocities associated with such paths. Hyperbolic searches for semblance among appropriately gathered arrays of traces form the basis upon which velocities are estimated. Measured semblances are presented as a velocity spectral display. Interpretation of this information can give velocities with meaningful accuracy for primary as well as multiple events. In addition, the velocity data can help correctly label events. This paper outlines the fundamental principles for calculating velocity spectra displays. Examples are included which demonstrate the depth and detail of geological information which may be obtained from the interpretation of such displays.
