FIG. 2-7 INDIRECT ECHOES
2.5.3 Multiple Echoes
The multiple echoes may appear if there is a large target having a wide vertical surface
parallel to your own ship at comparatively short ranges. The signal will be reflected by
the wide vertical surface, then the reflected signal strikes your own ship, and it will return
along the same paths to the target. This will be repeated.
Thus, the multiple echoes will appear beyond the true target's echo on the same bearing
as shown in Figure 2-8.
