UNDERSTANDING RADAR AND LASER
RADAR SPEED MONITORING SYSTEMS
Three band frequencies have been approved by the Federal Communications Commission (FCC)
for use by speed monitoring radar equipment:
X band 10.525 GHz
K band 24.150 GHz
Ka band 33.400 – 36.00 GHz
LIDAR (LASER)
The correct name for the technology that most people refer to as laser is actually LIDAR, which
stands for Light Detection and Ranging. LIDAR operates much like radar. Its signal spreads out
like a radar signal, though not as widely.
Unlike radar, LIDAR must have a clear line of sight to its target vehicle throughout the entire
measurement interval. Obstructions such as signposts, utility poles, tree branches, etc., will
prevent valid speed measurement.
Some common questions about LIDAR include:
Does weather have any effect on LIDAR?
Yes. Rain, snow, smoke, fog or airborne dust particles will reduce the effective range of LIDAR
and can, if dense enough, prevent its operation.
