摘要
根据水声瞬态信号检测的特点,研究了基于高阶谱的power-law算法及其在水声瞬态信号检测中的应用。模拟试验和实际数据处理结果表明基于高阶谱的power-law瞬态信号检测器在检测非高斯瞬态信号方面优于传统的基于DFT的power-law检测器,有较好的应用前景。
We develop the power-law processor operating on higher-order spectrum domain and apply the method to detect underwater transient acoustic signals. The simulation examples and experimental results indicate that the proposed power-law detector based higher-order spectrum outperforms conventional detectors used to detect non-Gaussian transient signals.
