Abstract
The problem of detecting a narrow-band underwater sound source within a specified region is considered. The method requires the subdivision of the surveillance region into a finite set of grid points as potential source locations. Sensors are distributed arbitrarily within the region. A test statistic, optimal in the Neyman-Pierson sense for simple hypothesis testing at each location, is derived under the assumption that the relative signal amplitudes and phases are known at the sensors for each candidate source location. Statistical properties of this stochastic variable are derived. The correlations between tests statistics are derived as functions of signal-to-noise ratio.
