Figure 2. Characteristics of the reflected signal according to the incident angle (IMAGE)
Caption
(A) If the object is small or has a linear structure, the waveform of the reflected signal of the single scattered waves remains similar even when the incident angle is changed. (B) However, the waveform of the reflected signal of the multiple-scattered waves changes without similarity even with a slight change in incident angle. Using these inter-wavefront properties, single scattering components and multiple scattering components can be separated from each other.
