Locally optimum network detection of unmodelled gravitational wave bursts in an impulsive noise background

摘要

Locally optimum network detectors of weak unmodelled gravitational wave bursts in non-Gaussian noise are introduced. Robust implementations coping with non-stationarities and/or uncertainties in the impulsive (glitch) noise component are discussed. Their performance is evaluated, capitalizing on a simple model for the glitch-noise component, with specific reference to a three-detectors (LIGO-Virgo) observatory.
