本文讨论一列平面波与一列平面行波脉冲的声相互作用，显然这两个波不仅都满足波动方程，而且可以用来讨论公共区之外的声散射声问题。
In this paper, the interaction between a cw plane wave and a plane pulse travelling with sound speed is considered. Both of them satisfy the homogeneous wave equation.
本文应用一致性时域有限差分法（FDTD）和近场远场变换计算散射声目标的反射声压强度，找出反射声压级与目标声中心到换能器间距离的关系。
Using the finite difference time-domain (FDTD) method and near field to far field transformation, pressure of the reflected sound from the scattering target is calculated.
本文还考虑了界面状况对声散射的影响。
The effects of the boundary condition on sound scattering are also considered.
