The study of sound scattering from solid targets near a water-sediment interface is a topic of recent interest. Keeping in line with this direction of study, the following is an investigation of the various acoustic scattering mechanisms from a solid aluminum cylinder in broadside geometry near a flat air-water interface. In addition to identifying the possible scattering interactions that can occur, contained in this article is the explanation of the various methods utilized to investigate the different physical processes. Furthermore, the following treatment will utilize the geometrical optics approximation to treat targets as point particles to perform a simple analysis of the processes in the time domain. Although this approach is useful, it will not completely describe all aspects of the interactions but will provide a cursory understanding of the timing relations of the different identified mechanisms and will give an explanation of acoustic feature loci of a variety of possible scattering mechanisms.

双基地声散射的时间演化：平面界面附近侧边圆柱体的机制位点识别


研究水-沉积物界面附近固体目标的声散射是最近人们感兴趣的一个话题。与这个研究方向保持一致，以下是对平坦空气-水界面附近的侧面几何形状的实心铝圆柱体的各种声学散射机制的研究。除了确定可能发生的散射相互作用之外，本文还解释了用于研究不同物理过程的各种方法。此外，接下来的处理将利用几何光学近似，将目标视为点粒子，对时域过程进行简单分析。虽然这种方法很有用，但它不会完全描述相互作用的所有方面，但会提供对不同识别机制的时序关系的粗略理解，并将给出各种可能的散射机制的声学特征位点的解释。
