EVALUATION OF THE CPO AUXILIARY PROCESSOR
Abstract
Both routine operation of the Cumberland Plateau Seismological Observatory and considerable applied research were conducted. During the last project year, on-line real-time detection and identification processing using the CPO Auxiliary Processor was implemented and evaluated at CPO for the purpose of studying automatic detection processing. The CPO Auxiliary Processor computes two classes of detection outputs, the Fisher analysis of variance statistic and the Wiener power statistic, and one class of identification output, the United Kingdom technique. These detection outputs were compared online against a fixed signal threshold level, providing a continuous real-time yes-no output for signal. However, the fixed-threshold detection levels were initially difficult to determine accurately and, once determined, it was found that they were highly non-time stationary. Adaptive threshold detectors incorporated into the Auxiliary Processor could overcome the non-time stationariness of the threshold detectors. Off-line applied research was performed to support the on-line research.
