摘　　要：在分析可靠声路径(RAP)的物理机理的基础上,将RAP与时间反转处理相结合,研究了基于RAP的垂直水听器阵时反定位问题,并在Munk声速剖面下的进行了仿真分析,结果表明了利用RAP进行垂直线列阵时反定位的有效性,通过适当提高阵元数量和间距可增强时反聚焦效果。On the basis of analyzing physical mechanism of reliable acoustic path （RAP） and time reversal processing is combined. Time reversal positioning problem of vertical hydrophone array based on RAP is researched. Simulation analysis under the condition of Munk sound speed profile is carried out, and the result shows validity of positioning of vertical line array based on RAP, improving sensor number and distance between sensors can enhance time-reversal energy focus effect.
