根据水声技术的发展,特别是水下相控基阵的使用推广,人们发觉水声基阵的实际设计和使用存在许多问题有待解决。经研制组科技人员几年的刻苦攻关,该题完成了如下的研究成果:1)在换能器组成的相控接收阵中,阵元的声耦合作用和它对阵元指向性与相控接收阵指向性的影响,首次提出互耦合系数的计算方法,为设计多元相控阵提出定量的理论估计和设计参考。2)在声波作用下弹性—粘弹性复合障板声散射近场特性的理论和实验研究,提出了 According to the development of underwater acoustic technology, especially the promotion of the use of underwater phased array, people find that there are many problems to be solved in the actual design and use of underwater acoustic array. After years of research and development team of scientific and technical personnel assiduously, the title completed the following research results: 1) In the phase control receiver array composed of the transducer, the acoustic coupling of the array element and its array element directivity and phased receive For the first time, the calculation method of mutual coupling coefficient is proposed, and a quantitative theoretical estimation and design reference for designing a multi-phased array is proposed. 2) Theoretical and experimental studies on the acoustic scattering near-field properties of elastic-viscoelastic composite baffles under the action of acoustic waves
