How Radar Works

Traffic radar, which consists of microwaves, 
travels in straight lines and is easily 
reflected by objects such as cars, trucks, 
even guardrails and overpasses. Radar 
works by directing its microwave beam 
down the road. As your vehicle travels into 
range, the microwave beam bounces off 
your car, and the radar antenna looks for 
the reflections. Using the Doppler Principle, 
the radar equipment then calculates your 
speed by comparing the frequency of the 
reflection of your car to the original 
frequency of the beam sent out.
 

Traffic radar has limitations, the most 

significant of these being that it typically 
can monitor only one target at a time. If 
there is more than one vehicle within 
range, it is up to the radar operator to 
decide which target is producing the 
strongest reflection. Since the strength of 
the reflection is affected by both the size of 
the vehicle and its proximity to the 
antenna, it is difficult for the radar operator 
to determine if the signal is from a sports 
car nearby or a semi-truck several hundred 
feet away.
 

Radar range also depends on the 

power of the radar equipment itself. The 
strength of the radar unit’s beam 
diminishes with distance. The farther the 
radar has to travel, the less energy it has for 
speed detection.

 

Because intrusion alarms and motion 

sensors often operate on the same 
frequency as radar, your V995 will  
occasionally receive non-police radar 
signals. Since these transmitters are usually 
contained inside of a building, or aimed 
toward the ground, they will generally 
produce much weaker readings than will a 
true radar encounter. As you become 
familiar with the sources of these pseudo 
alarms in your daily driving, they will serve 
as confirmation that your V995’s radar 
detection abilities are fully operational.

How “POP” Works

“POP” mode is a relatively new feature for 
radar gun manufacturers. It works by  
transmitting an extremely short burst, 
within the allocated band, to identify 
speeding vehicles in traffic. Once the target 
is identified, or “POPPED,” the gun is then 
turned to its normal operating mode to 
provide a vehicle tracking history, (required 
by law).

How Laser (Lidar) Works

Laser speed detection is actually LIDAR 
(Light Detection and Ranging). LIDAR guns 
project a beam of invisible infrared light. 
The signal is a series of very short infrared 
light energy pulses, which move, in a 
straight line, reflecting off your car and 
returning to the gun. LIDAR uses these light 
pulses to measure the distance to a vehicle. 
Speed is then calculated by measuring how 
quickly these pulses are reflected given the 
known speed of light. 
 

LIDAR (or laser) is a newer technology 

and is not as widespread as conventional 
radar, therefore, you may not encounter 
laser on a daily basis. And unlike radar 
detection, laser detection is not prone to 
false alarms. Because LIDAR transmits a 
much narrower beam than does radar, it is 
much more accurate in its ability to 
distinguish between targets and is also 
more difficult to detect. 

AS A RESULT, 

EVEN THE BRIEFEST LASER ALERT 

SHOULD BE TAKEN SERIOUSLY.

 

There are limitations to LIDAR 

equipment. LIDAR is much more sensitive 
to weather conditions than RADAR, and a 
LIDAR gun’s range will be decreased by
anything affecting visibility such as rain, fog, 
or smoke. A LIDAR gun cannot operate 
through glass and it must be stationary in 
order to get an accurate reading. Because 
LIDAR must have a clear line of sight and is 
subject to cosine error (an inaccuracy, 
which increases as the angle between the 
gun and the vehicle, increases) police 
typically use LIDAR equipment parallel to 
the road or from an overpass. LIDAR can be 
used day or night.
