User's Manual

Mounting Bracket
Mounting bracket should allow for sufficient adjustment of the radar pointing angle and
height. At the very minimum some degree of adjustment for the vertical angle should be
provided. The user must perform a “boresight” check to validate that the radar beam is
pointed correctly. Adding a guide fixture to facilitate boresight check is a good idea. If
boresighting is not feasible you may choose to provide means to temporarily attach an
inexpensive USB camera for the initial setup. As a last resort you may pre-calculate the
required mounting angle and make sure that the bracket provides it.
Installation must also ensure that the radar is rigidly mounted. Support structures that are
affected by wind are not a good choice. Swaying action changes radar’s field of view and
affects the performance. Note: highway mode is less susceptible then intersection mode
due to lower sensitivity and range resolution.
Location
Places that have a lot of wall area such as tunnels and overpasses are not a good location
for the radar. Walls can bounce the radar beam and create ghost targets.
Note: when beam bounce or multi-pass propagation creates ghost targets it is sometimes
possible to adjust the radar location in such way that these ghost targets would fall
outside of the user defined lanes and thus be discarded. Supplied Windows Configuration
Utility should always be used to verify the setup.
Setback and Mounting Height
In the side fire multi-lane installation the radar must be mounted in such way that it may
see over the top of the closer vehicles. This requires it to be mounted higher than the
tallest vehicle it will encounter in a closer lane. An exception to this rule is a situation
where you are detecting only the closer lane, e.g. a turn lane. In which case the radar can
be mounted at target height and pointed horizontally.
For optimal performance, the setback must be increased with the mounting height as
suggested in the table below. Insufficient setback may result in lane misdetection for the
closer lanes.
