Figure H-3 below
shows two sensors mounted on a vehicle. The sensor mounted on the car’s left side has its phase lock
offset set to 90°, and the phase lock offset of the sensor mounted on the right side of the vehicle is set to 270°, as shown by
the red arrows.
Figure H-3 Right and Left Sensor Phase Offset
When sensors are placed on the roof in the fore and aft positions, the phase offsets are set to 180° and 0° as shown in
Fig-
ure H-4 below
.
Figure H-4 Fore and Aft Sensor Phase Offset
In both scenarios the two sensors create data shadows behind each other.
To avoid any spurious data due to blockage or reflections from the opposing sensor, the user should ignore any data in the
shadowed azimuth ranges as shown in
Figure H-5 on the facing page
. To do that, you need to know the diameter of the
sensors (see
Sensor Specifications on page 90
) and distance between the sensor centers.
