INSTALLATION
RADAR INSTALLATION - RED LIGHT ENFORCEMENT (RECEDING FLOW)
This diagram shows the potential beam coverage of the
350 Radar being used to monitor an intersection for red
light enforcement. The ‘D4’ distance is an important
consideration when adjusting mounting parameters of
the radar.
Adjusting mounting height, offset and mounting angle
will all have the effect of increasing or decreasing the
‘D4’ value. The value is defined as the initial point of
radar coverage on the surface of the roadway. See
diagram below.

350 Radar Installation Analysis (beam coverage)
D4 - This distance is approximately four metres based on suggested
parameters but is variable.
Initial point of radar coverage
on road shifts upon adjustment
of radar height.
