Understanding Radar, Laser and SWS

Three Radar Frequencies

 

Three microwave frequencies have been allocated by  

 

the FCC (Federal Communications Commission) and  

 

are used for traffi c Radar. They are:

 

 

X band: 10.45–10.60 GHz

 

  K band: 24.050–24.250 GHz

 

  Super Wideband Ka: 33.4–36.0 GHz

 

Both X and K bands are well known to motorists who  

 

have traveled with Radar detectors. Introduced fi rst  

 

was X band Radar which became common during the  

 

1960s. In the mid 1970s, the lower powered, more   

 

diffi cult to detect K band Radar was introduced. In    

 

1987, FCC approval was given for use of Radar  

 

 

equipment using a third frequency, Ka. In response to  

 

this, BELTRONICS introduced the fi rst Radar 

 

detectors capable of detecting X, K and Ka band 

 

signals. In late 1990, FCC approval was given to 

 

Wideband Ka: 34.2 GHz to 35.2 GHz. Once again, 

 

BEL responded with Wideband Ka detection. Today, 

 

your 975e can detect Super Wideband Ka. To turn 

 

this on, see selectable options section.

Safety Warning System (SWS) – What is it?

 

The Radio Association Defending Airwave Rights, Inc.  

 

(R.A.D.A.R) conceived and developed the Safety    

 

Warning System. The concept behind this system is to 

 

warn motorists of potential road hazards by 

 

employing Safety Warning System transmitting 

 

devices in areas such as construction zones, accident  

 

sites and detours. Because these SWS transmitters 

 

operate within the 24 GHz portion of the K band 

 

frequency, their signals are detected by your unit.

Interpretation of Alerts

Radar Alerts

 

The alerts provided by your unit are affected both by  

 

the type of transmission (continuous wave or instant- 

 

on) and the position of the Radar source. Generally,  

 

when you drive closer to a Radar source the intensity  

 

of the received signals increases, resulting in a greater  

 

number of LEDs illuminating in the four-LED display   

 

(l or r) and a corresponding increase in the audio    

 

alert rate. Described on the following pages are fi ve  

 

common types of Radar encounters and the alerts you 

 

will typically receive.

1.  Stationary or moving Radar, straight ahead aimed in your 
 direction.
