Signal Enhancement of LPE Data

Abstract

In this report the authors investigate signal/noise ratio enhancement obtainable on single-station LPE recordings by several techniques. The processors which are compared over a data base of 20 events include simple band- pass filtering, match filtering with a synthetic LR signature, and time-varying non-linear processing which examines three-component data for Rayleigh-wave characteristics. For the suite of events in this study, average S/N ratio improvement is 6 db for match filtering, 15 db for the non-linear PHILTRE processor and 20 db cascading the two processors.
