Here is a strange explanation of how to reduce ground clutter.
The pattern up and down (relative to the picture in the book – looking at the component side with wires on left) is not symmetrical. The sonar is much more sensitive to objects below boresight. So if you are mounting your sonar vertically (not side-by-side), mount it up-side-down. And in any case, aim the sensor UP about 30 degrees or more to avoid the ground. Probably the mounting supplied can be bent.

Could someone draw a sketch about what's meant.
