Evaluation of Two Automatic Signal Detectors Using the Korean Seismic Research Station Short-Period Array.

摘要

Fisher and conventional automatic seismic signal detectors were evaluated for their detection performance with data from the Korean Seismic Research Station (KSRS). A total of 330 events recorded in November 1974 and January-February 1976 was used as a data base. The detectors were run with 0.8 and 1.6 second integration gates. The capability of both detectors to successfully detect and time seismic events was compared with the performance of a seismic analyst. The author found the conventional (array beam) power detector superior to the Fisher detector. A conventional power detector installed at KSRS could achieve a seismic analyst's detection performance, but possibly at a higher false alarm rate than the analyst.
