K band radar false alarms

K band alert? Slow down, but it may be a false alert . K band radar are radar waves that fall between 18 GHz and 27 GHz, with most of the law enforcement radar guns operating at 24.125 GHz and 24.15 GHz. Police radar began detecting with K band a few decades after X band was introduced.

Sometimes your radar detector gets set off by things that aren’t radar or laser enforcement devices. These “false alerts” are usually caused by automatic door openers, roadside traffic monitors and electronic warning signs, emergency vehicles, and in-vehicle technologies (IVT) .

First, it means that there will be times when the user drives by a police officer and the radar detector does not alert. The most common cause of this is simply that the officer is not operating a radar gun at this time , which means the radar detector has no way to detect the officer’s presence.

In town, commercial automatic door openers routinely cause false alerts. Other K-band false alarms are caused by traffic-sensing radar (TSR) that monitors traffic flow and volume. Many newer detectors recognize TSR radar and GPS-enabled models can lock out door-opener radar.
