Police Radar FAQ’s
What’s the Difference Between Stationary and Moving Modes?
Stationary mode is useful if you want to scan traffic while parked on the side of the road. This technology has been used since police radar was invented.
Moving mode is used to monitor traffic speeds while the patrol car is moving. This is a more advanced technology, as the radar has to be able to figure out how fast the patrol vehicle is moving, and then figure out how fast or slow other vehicles are moving relative to the patrol vehicle speed.
All of Stalker Radar’s dash mounted radar systems and also the Stalker II MDR hand-held police radar gun include both stationary and moving modes standard.
What is Directional Radar?
Directional radar technology allows the patrol officer to measure the speeds of vehicles moving towards the radar or away from it, or even monitor both directions simultaneously. By allowing you to choose which mode you are using at any given time, Stalker Radar products allows for more precise and accurate targeting.
Can Radar Work in Rain and Snow?
Precipitation in any form (rain, hail, sleet, and snow) can reduce the distance at which vehicles can be detected, but it does not affect the accuracy of the readings themselves.
Does Radar Work at Night?
Yes. Radar is not dependent on light at all, and so it offers the same accuracy whether used at night or during daylight hours.
What is the Difference Between K-Band and Ka-Band Radar?
The difference between K- and Ka-Band radar comes down to the frequency of the signal. Technically, the K-band frequency is 24.150 GHz, and Ka-Band ranges from 33.4-36.0 GHz. Because the frequency of Ka-Band radar is higher, the antenna that pick up those signals can be smaller.
