Occlusion and Multipathing

These are two problems you might face while using a radar detector.
Occlusion occurs when one object blocks another object from the sen-
sor's view, as shown above. This can happen with
Tall vehicles like semi trucks

Barriers and sounding walls

Trees and more

Multipathing occurs when a large flat surface near the sensor interferes
with detection. A radar signal can bounce around several times between
the surface and the vehicles before returning to the sensor. This can
make the sensor detect a vehicle where there is none.
This can happen with
Buildings

Fixing occlusion problems

Move the sensor higher on the pole (keeping it within the recom-
˿
mendations in the mounting height and offset table).
Move the sensor to another spot if possible, away from obstructions.

Note. A good rule of
thumb is that 50%
of a vehicle must
be visible above
any barrier in order
to be detected..
