Seismic Signal Detection Algorithms

Abstract

This report covers the procedures undertaken and the results obtained during an 18-month program to implement and test an automatic seismic event detection algorithm that is based on the Walsh transform. The algorithm was successfully implemented and tested on a Z80A-based microcomputer, and the system was placed in operation at the Norwegian Seismic Array (NORSAR) for on- line evaluation. The results of the system operation and effectiveness is presented. Also included is a report of the performance of the detection algorithm in off-line tests utilizing standard tapes prepared under AFTAC/VSC supervision.
