Extended Array Evaluation Program. Special Report No. 16. Preliminary Comparison of Automatic Fisher and Conventional Power Detection Algorithms

Abstract

The performance of two seismic event detectors, the Fisher detector and the conventional power detector, was compared. Long-period records with low signal-to-noise ratios, recorded at the Alaskan Long Period Array, were used to establish performance characteristics, sensitivities, response to off-azimuth events, and response to signal distortion. Results confirmed the theoretical prediction that there is no important distinction between the detectors.
