| 摘 要： | 采用现代信号处理技术及水声物理学的交叉内容形成匹配场处理技术，用来进行声源定位。运用数值方法进行简正波分解得到各阶简正波的特征值与特征函数，进而求得远距离声场，并采用Bucker检测因子(DF)方法对假定声源进行了计算机定位仿真。这一方法，具有精度高、低频计算快的特点，特别是在远距离有关的环境。

| Abstract: | Modern signal processing and acoustic physic techniques were used to form a matched-field processing. The eigenvalues and eigenfunctions of the normal modes by employing a numerical method were obtained. The computer simulations by DF method were carried out for two scenarios in typical acoustic waveguide environment. The calculation specd of this method is faster in low frequency, it can be used in remote environment at a great distance. |
