A Three-Component, Single-Station, Maximum-Likelihood Surface Wave Processor

Abstract

An entirely analytic single-station surface-wave processor is developed that analyzes long-period seismic records two orders of magnitude faster than real tme on an IBM 360/44 computer. In processing four days of continuous synthetic data the algorithm detected 85% of the 170 signals of S/N = 1/2, with false alarm rate of one per day. A novel detection theory is introduced that exploits the consistency of the azimuthal estimates associated with a sequence of detections. (Author)
