Evaluation of the Improved Three-Component Adaptive Processor

Abstract

Evaluation of the original three-component adaptive processor revealed that improvements in signal-to-noise ratio are much greater for Rayleigh waves than for Love waves. A new algorithm has been proposed for Love wave processing to put the effectiveness of the Love wave processor on a par with that of the Rayleigh wave processor. This new algorithm tracks the incoming Love in azimuth and passes its entire duration. In addition, energy from azimuths outside some pre-set limit is rejected in a form of azimuthal filtering. In this report, expected signal-to-noise ratio gains over the bandpass filter are determined for both the original and new versions of the three-component adaptive processor. Detection threshold improvements are then determined by applying both versions to two event suites. The evaluation is performed for both single-site and beam data.
