利用快速而准确计算海洋声场的广义相积分(WKBZ)简正波方法,研究在深海声道中进行匹配场定位的可能性。使用窄带脉冲声信号和宽带爆炸声以及27.5m和32.5m长的垂直短阵在深海声道中进行了实验,实验结果的处理和分析表明,对几百赫兹的声信号用垂直短阵来实现匹配场定位是可能的。
The WKBZ normal wave method is used to calculate the ocean sound field rapidly and accurately, so as to study the possibility of matching field location in the deep-sea channel. Experiments were conducted in deep-sea channels using narrow-band impulsive acoustic signals and broadband explosions and vertical arrays of 27.5 m and 32.5 m. The processing and analysis of the experimental results show that acoustic signals of several hundred hertz are realized with vertical arrays Matching field positioning is possible.
