| 摘要: |
| 为了解决深海会聚区目标及其运动态势难以判断的问题,在对会聚区形成条件及其声场传播规律研究基础上,基于波导不变量理论,对典型深海环境不同位置距离-频率干涉条纹特征的进行理论分析和仿真验证。理论分析和仿真结果表明,深海会聚区存在与其他区域不同的干涉条纹特征,其对应的波导不变量 值为负。提出了利用会聚区特有的干涉条纹特征,对会聚区目标及其运动态势进行初步判断的方法,仿真结果和试验数据表明,判断方法可行有效。 |

| Abstract: |
| In order to solve the problem how to judge whether target is in convergence zone (CZ) and the target movement in CZ, analyzing formation conditions of CZ and its acoustic propagation, characters of waveguide invariant in deep-ocean were analyzed based on waveguide invariant theory and simulation tests performed. The theoretical analysis and simulation results both show that there are special waveguide invariant striations in CZ and valve of its waveguide invariant is negative. Making use of these characters, the method to judge whether target is in convergence zone (CZ) and the target movement in CZ is proposed and simulated. The simulation and experimental data both show that the judgment is valid. |
