Noise-Source Detection in an Oceanic Waveguide Using Interferometric Processing

Abstract

The signal-to-noise ratio as a result of interferometric processing of noise-source field in an oceanic waveguide is estimated. The minimum duration of noise-source realization, which determines the maximum noise immunity, is evaluated. The noise-source signal detection based on the Neyman–Pearson criterion is considered. The range of input signal-to-noise ratios for the case where a single detector provides acceptable data on the source parameters is analyzed. An expression for the detection curves (dependences of the correct-detection probability on the signal-to-noise ratio at a fixed false-alarm probability) is derived. The corresponding numerical calculations are carried out.
