Planar Array Bearing Estimation Performance Bounds

摘要

The Weiss-Weinstein bound on bearing estimator mse is evaluated for planar arrays possessing near-circular symmetry and simpler triaxial single-station instruments. The bounds suggest superior bearing estimation performance of small-aperture seismic arrays when contrasted with the simpler instruments, particularly in the threshold SNR region. The results have implications for the composition of a seismic network that might be deployed to verify nuclear test ban treaties. 4 refs., 6 figs. (ERA citation 13:037635)
