Are you thinking about joining the millions of American drivers who use a police radar detector to avoid getting saddled with a costly speeding ticket? Welcome to the world of high-technology that enables persons just like you to be alerted when a police scanning radar is nearby.
What police radar is and how it works
Many people ask us what the term 'radar' means. The word is an acronym for RAdio Detection And Ranging. Unlike the laser devices utilized by traffic enforcement officers, a police radar evaluates and reports a nearby vehicle's velocity by detecting something called the Doppler shift. You've undoubtedly heard the Doppler effect when a train passes by and recedes or when you pass a musical ice cream truck on the road. Doppler radar can also be seen on virtually any nightly broadcast news weather report.
Police radar may be operated from within a moving cruiser or while parked. Many traffic enforcement cars are outfitted with both front- and rear-facing radar transmission devices. Because of this, it is crucial to remember that a cop car in front of you can tell how fast you're going. It is also worth noting that police radar may be operated in unmarked patrol cars.
How police radar operates
A typical police radar may be operated continuously or turned on and off as the traffic officer chooses. Continuously transmitted radar, or CO, is easily 'seen' by a good police radar detector such as the ones we make and sell here at Rocky Mountain Radar. Nonetheless, there may be certain situations where this type of radar traffic enforcement apparatus may be somewhat harder to detect, such as when a police officer operates the device from a covered position such as dense foliage along the roadside or in a highway median.
Instant-on police radar, also known as RF-hold or IO radar, made its debut in the very early 1980s, right around the time that the first commercial police radar detector came on the market. Coincidence? Probably not. Instant-on radar was designed to defeat drivers who have police radar detectors mounted in their vehicles. By the way, your detector cannot alert you to a police radar that isn't turned on.
Frequencies used by police radar
Detector devices look for police radar that operates on one of three frequency bands called the X-band, K-band or a super-wide Ka frequency band. Of these frequency bands, the X-band is the oldest.
If you install and activate a police radar detector, and if that device saves you from even one expensive speeding ticket, the thing will pay for itself. For drivers who spend a lot of time on the highway, a suitable detector can help them remain within the speed limit by reminding them when actively transmitting police radar is nearby.
