For a class of scattering objects the mean separation between the scatterers is determined. Over a range of frequencies, ultrasonic back-scattered pressure signals are recorded. It is suggested to derive the mean spacing of an unknown scattering object by employing Fourier analysis and comparing the signal with signals from known regular arrays of scatterers. In a computer simulation it is shown that this approach determines the mean spacing very well for random arrays consisting of three-dimensional spherical scatterers.
对于一类散射体，确定了散射体之间的平均间距。在一定频率范围内，记录了超声背向散射压力信号。建议通过傅里叶分析并将该信号与来自已知规则散射体阵列的信号进行比较，来推导未知散射体的平均间距。在计算机模拟中表明，这种方法对于由三维球形散射体组成的随机阵列能很好地确定平均间距。
