摘　　要：根据海洋声速分布特点,分析了基于可靠声路径算法的可达到的最大被动水声探测距离。通过声传感器垂直线阵列接收声线和最远探测距离,证明了深海环境可靠声路径算法可以实现声传感器垂直线阵列远程水声探测,通过对垂直线列阵阵元数的仿真,表明增加阵元数能够提高声传感器垂直线列阵的探测能力。研究结果为在深海环境下远距离探测提供了理论依据。According to the characteristics of ocean acoustic velocity distribution, the maximum range of passive acoustic detec-tion based on reliable acoustic path algorithm is analyzed. It is proved that the reliable acoustic path algorithm of deep sea environ-ment can realize the remote acoustic detection of acoustic sensor vertical line array by receiving the sound line and the farthest de-tection distance of the acoustic sensor vertical line array. The simulation results show that increasing the number of array elements can improve the detection ability of the vertical array of acoustic sensors. The results provide a theoretical basis for remote detection in deep-sea environment.Keywords： reliable acoustic path; vertical array; passive ranging; deep-sea detection
