| 摘 要： | 声对接技术以平面近场声全息理论算法为基础，利用声传播的近场特性，在一定的介质条件下来模拟声场远场传播特性的技术。在近场条件下，平面近场声全息技术能够针对不同的测试频率范围以及声场分布等要求，计算出相应的传输介质厚度以及对接阵阵元分布等参数，从而设计出声对接阵。通过仿真验证，采用平面近场声全息技术设计的声对接阵完全能够满足与水中兵器基阵实现声对接的要求。

| Abstract: | Based on the theory and algorithm of planar near-field acousitc holography,acoustic coupling technique is applied to simulate the far-field propagating character in a certain condition of medium material by the near-field propagating character.In near field the thickness of transmission medium and the element distribution of butt array can be figured out according to testing requirement of frequency and field distribution by planar near-field acoustic holography,and then acoustic butt array can be acquired.The simulation proved that acoustic coupling device based on planar near-field acousitc holography fully meet the demand of butt with the underwater weaponry. |
