摘　　要：本文重温了声散射和散射强度概念以及不同形状散射体的散射的理论分析结果。讨论了在实验室水槽中测试的三种材料、两种形状和不同尺寸反射体的散射图案的特征。The concepts of acoustic scattering and scattering strength of different acou- stic reflectors are reviewed in this paper. Theoretically analyzed results of the scattering of reflectors in different shapes are presented. The characteristics of the scattering of reflectors of different materials and in different shapes are discussed.
