中文摘要:
      根据水声瞬态信号的特点,在分析能量检测和高阶谱检测的特性基础上,研究了基于能量检测和基于高阶谱的Power-Law检测方法,将上述两种检测器联合构成一种双通道Power-Law检测器,更好地利用了水声瞬态信号中的统计信息。通过计算机仿真试验,证明了该检测器的有效性,它能在更大程度上适应复杂水声环境变化的要求,改善和提高水声瞬态信号的检测性能。
英文摘要:
      Through analysing characteristics of energy detection and high-order spectrum detection,methods of Power-Law detection based on energy detection and high-order spectrum are studied according to traits of underwater acoustic transient signals.For better use of statistic information in underwater acoustic transient signals,these two detectors are jointed to be a dual-channel Power-Law detector,which validity is proved through simulation experiments.It can adapt to more complex underwater acoustic environment and improve detection performance for underwater acoustic transient signals.
