摘要：
To systematically analyze bottom acoustic scattering properties and summarize their regularities, this paper presents a review of the associated research progress at home and abroad. First, the fundamental concept of bottom 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 discussed, noting that research on models of midfrequency and wide grazing angle bottom acoustic scattering is particularly essential to underwater offensive and defensive applications. © 2024 Editorial Board of Journal of Harbin Engineering.
