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.

海洋干涉仪中干涉仪的噪声源检测

摘要

通过对海洋波导中噪声源场进行干涉测量的结果，可以估算出信噪比。评估确定最大抗扰性的最小噪声源实现持续时间。考虑了基于Neyman–Pearson准则的噪声源信号检测。对于单个检测器提供有关源参数的可接受数据的情况，分析了输入信噪比的范围。得出检测曲线的表达式（正确检测概率与固定虚警概率下信噪比的关系）。进行了相应的数值计算。
