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 X-Band radar, your RX45 will 
occasionally receive non-police radar 
signals. Since these X-Band 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 RX45’s 
radar detection abilities are fully 
operational.
