A robust and coherent network statistic for detecting gravitational waves from inspiraling compact binaries in non-Gaussian noise

The robust statistic proposed by Creighton and Allen et al. for detection in stationary non-Gaussian noise is briefly reviewed. After restoring a contribution to this statistic that was absent in those analyses, we reinterpret the role of the resulting robust statistic. We then obtain the analogous robust statistic for detecting inspiral waveforms in a single detector. We also derive the coherent statistic for detecting such signals with an arbitrary network of earth-based interferometers. Finally, we show that excess computational costs incurred owing to non-Gaussianity is negligible compared to the cost of detection in Gaussian no
