Evaluation of the MARS Seismic Event Detector
Abstract
The Systems, Science and Software (S(3)) Multiple Arrival Recognition System (MARS) was run on two detection test tapes supplied by the VELA seismological Center (VSC). The tapes contain nearly 45 hours of phase- randomized seismic noise in which a total of 268 events were added at varying signal levels. Compared against an algorithm using 'optimum filters' which was run at the VELA Seismic Center, the MARS detector achieved a 13 percent greater detection probability (with no greater false alarm rate) on both test tapes. A subsequent analysis at VSC using fixed bandpass filters, however, yielded results comparable to those reported here. Running on a Univac 1100/81 computer, the algorithm operates about 40 times faster than real time. The majority of the time is consumed in Fast Fourier Transforms.
