| 摘 要： | 在浅海波导中,垂直阵可以跨越整个波导,并能对大多数简正波模态进行精确采样.在给定声源及海洋环境信息的条件下,通过MOATL简正波模型仿真计算出到达垂直时反阵位置处的波形,即垂直时反阵的接收信号,将接收信号时间上取反,通过以KRAKEN简正波模型计算得出的返回声信道,在声源处取得了较好的聚焦效果.并分析了垂直阵基元数、基...

| Abstract: | Vertical linear array can span the whole wave-guide and can sample most normal modes accurately in the shallow water wave-guide.This paper introduces a method that is using MOATL normal mode to simulate a signal in the place of vertical linear array as its take-over signal.Then reverse this signal and make it pass through the reverse wave channel modeled by KRAKEN normal mode.Obvious retrofocusing effects can be seen in the place of sound source.Then the paper analyses how retrofocusing effect changes when ... |
