摘要

作者量化了应用于浅水传播的水声瞬态的宽带二、三、四阶累积量和基于矩的检测器的性能。通过对真实数据的仿真，得到了所选虚警率的检测概率与信噪比(SNR)的关系。在信噪比为-20 ~ 5 dB的范围内，四阶检测器的整体性能优于二阶(能量)和三阶检测器。

Experimental performance of some higher-order cumulant detectors for hydroacoustic transients

The authors quantify the performance of broadband second-, third-, and fourth-order cumulant and moment based detectors applied to hydroacoustic transients transmitted through shallow water. Through simulations on real data they obtain probabilities of detection as a function of signal-to-noise ratio (SNR) for chosen false alarm rates. In the investigated SNR range -20 dB to 5 dB the overall performance of the fourth-order detectors is superior to that of the second-order (energy) and third-order detector.<>
