INSTALLATION
RADAR MOUNTING HEIGHT
The radar can be installed at different heights but operation is best in the height range 1m to 3.5m. The radar
can be mounted up to a height of 5m but it is important to understand that at these higher mounting heights the
vertical cosine will affect the speed reading of the radar to progressively under-read for increasing heights for
lanes that are too close to the radar.
It is therefore recommended that a minimum off-set, that is, a minimum perpendicular distance from the
mounting position to the nearest enforceable lane is adopted as shown in the following table.
SELECTING A SUITABLE SITE
When choosing to deploy the radar on a site the following is a non-exhaustive list of considerations which should
be taken into account;

RADAR MESSAGES IN NORMAL OPERATION
When the radar is installed and aligned correctly it will perform to specification.
