摘要
提出Bootstrap方法的水声信号检测技术,将Bootstrap方法的数字仿真与经典统计学有机结合起来,利用小子样数据进行统计计算。对信号处理中的统计指标准确度进行评估并对小样本情况下参数值进行估计。采用高斯白噪声背景下的单频信号检测,对所研究的方法进行仿真验证。结果表明,该方法在进行水声信号的检测时是可行的、有效的。
A underwater acoustics signal detection technology based on Bootstrap method is presented, Digital simulation in the Bootstrap method is combined with the classical statistics. The statistics calculation is done in this approach by using small samples and the problems of conventional statistical calculation are solved. This method is usually used in the statistics evaluation and parameter estimation in the signal processing. A calculation example of the single frequency signal detection based on white Gaussian noise is given to prove its feasibility and efficiency. Simulating results show that the satisfying effects are gained by using the proposed method in the underwater acoustics signal detection.
