摘要
为了对海底声散射特性进行系统分析和规律总结,本文梳理了国内外有关海底声散射特性的研究进展.介绍了海底声散射的基本概念,并对界面粗糙散射及沉积物体积散射的理论模型进行了总结;从高频(>10 kHz)和中频(1～10 kHz)2 个方面阐述了国内外典型海底声散射特性测量实验,同时对当前具有代表性的海底声散射实验结果进行了归纳分析.最后剖析和探讨了当前海底声散射研究中存在的问题和未来发展方向,并指出海底中频及宽掠射角声散射模型研究在水下攻防应用中尤为紧要.
Abstract
To systematically analyze bottom acoustic scattering properties and summarize their regularities,this pa-per presents a review of the associated research progress at home and abroad.First,the fundamental concept of bot-tom acoustic scattering is introduced,drawing a conclusion on existing associated theoretical models for interface roughness scattering and sediment volume scattering.Then,typical measurement experiments with regard to the scattering properties worldwide are expounded from two aspects,high frequencies(>10 kHz)and midfrequencies(1～10 kHz),sorting out the currently representative results of bottom acoustic scattering experiments.At last,the problems in the current bottom acoustic scattering research and future research directions are analyzed and dis-cussed,noting that research on models of midfrequency and wide grazing angle bottom acoustic scattering is particu-larly essential to underwater offensive and defensive applications.
