ACOUSTIC VOLUME
The ARIS multi-beam sonar projects a wedge shaped
volume of acoustic energy much like a flashlight projects
a cone shaped volume of light.

PERSPECTIVE VIEW
RANGE, CROSS-RANGE & IMAGE PERSPECTIVE
Three terms concerning distance and direction relative to the acoustic wedge are Range, Cross-Range, and Image
Perspective. Each of these are at 90 degrees to the other two, much like the 3 edges that come together at the
corner of a box. Range refers to distance away from the ARIS along the length of the wedge. Cross-Range speaks to
distance directly across the width of the wedge. Image Perspective speaks to direction coming from above viewing
directly down on the wedge.
