本笔记记录了一种处理一套接收函数(RF)走线的方法,以便根据其相关混响的时序识别非连续性生成的p -to- s (Ps)转换。它的灵感来自库马尔和博斯托克估算绝对波速的方法。根据直接对应物的典型源范围内记录的射频估计,该方法可以在不知道地壳vpor厚度的情况下获得spto波速比(VP/VS)。
This note documents an approach to process a suite of receiver function (RF) traces in order to identify discontinuity-generatedP-to-S(Ps) conversions based on the timing of their associated reverberations. It is inspired by Kumar and Bostock's method to estimate absolutePwave speeds. From RF estimates recorded in the typical source range for directParrivals, the method yieldsPtoSwave speed ratios (VP/VS) without knowledge of crustalVPor thickness.
