Detection of signals at the output of gravity resonance antennas by estimation of the distribution parameters

The statistical problem of detection of a useful vector signal at the output of resonance spatially-separated gravitational antennas with overlapping directional patterns is considered. A method involving estimation of the distribution parameters of the additive noise at the output of an optimal linear system of whitewashing and matched filters is used to solve the problem. The additive noise is assumed to be a mixture of correlated Gaussian noise and rare random pseudo-gravitational signals (minimax detection criterion).
