提出了一种当运动目标位于前向散射覆盖范围内时的距离估计方法。它是基于运动目标的前向散射引起的稳定到达的声场像差。通过连续传输信号来测量声场像差的持续时间，然后在假设运动速度的先验知识的情况下估计运动对象的距离。经过匹配滤波后，实验数据的声场像差观察得很清楚，估计的目标距离与真实值吻合较好。
A range estimation scheme is proposed when a moving object is located within the forward scattering coverage. It is based on acoustic field aberrations of the stable arrival caused by forward scattering of the moving object. The durations of acoustic field aberration are measured by transmitting a signal continuously, and then the range of the moving object is estimated if a priori knowledge of the moving speed is supposed to be known. The acoustic field aberrations of the experimental data are clearly observed after matched filtering, and the estimated ranges of the object agree well with the true values.
