They have never let me down.As the largest state in the lower 48, Texas is a land filled with many different perspectives, cultures, and influences. I have RMR units in every vehicle we own. A couple of miles per hour over and that's the gonna get you a ticket. My RMRs are reminders to keep a very close eye on exactly just what my speed is. They commonly have speed limits on the open back roads highways at 40 mph or less and vigorously enforce those limits. In Ohio, Pennsylvania, West Virginia as with most of the states up in the north east. My wife madethe comment "You bought these just so you can speed". We put on a lot of miles traveling across the country and encounters a lot of communities out to cash in on out of state vehicles. I have given RMRs as Christmas gifts in yesrs past to my adult sons whom also work within the oilfields across America. I have owned multiple RMR products and honestly feel naked without one in my vehicles. With my RMR units.I don't give them a reason to pull me over. Pennsylvania has a reputation for picking on out of state vehicles. This job has me working out of state the majority of the time. My job has me averaging well over 100,000 miles per year driving my own pickup. You csn always count on knowing a cop is lurking in the shadows.Īfter several years of driving a truck, I switched jobs and began working in the oilfield. This was snd continues to be a radar trap 24/7. Mysteriously seemed to stop working every time I drove through his town on I-35. The cop pulled me over wanting to know what I was doing to his radar. The only traffic stop was by a city cop from a town of which I drove through on.a regular basis. It seemed like "Bull Racks" were a prized catch for law enforcement. I virtually lived in that truck averaging over 250,000 miles per year. We were expected to get the livestock delivered fast and alive. At thst time I drove over the road hauling cattle. I'm not sure the exact year I purchaded my first unit. We have had Rocky Mountain Radars for msny years.Since this pulse train is continuous, there is no need for detection prior to activation greatly enhancing the probability of effectively confusing the LIDAR! This method makes Laser Speed measurement both ‘near-sighted’ (cannot ‘see’ pulses beyond 125 feet) and overwhelms the computer with confusing data so it cannot determine an accurate speed. Rocky Mountain Radar’s Laser scrambler creates 40 nano-second pulses every 125 nanoseconds (30 - 50 feet) to thoroughly confuse the LIDAR resulting in no speed being displayed. This requires much lower power transmission and is safer for the driver. This method creates infrared pulses virtually identical to those transmitted by the LIDAR. The second method, employed ONLY by Rocky Mountain Radar, is much more effective but more costly to manufacture. Of course, simple filtering of the incoming signals makes these types of jammers relatively ineffective. This takes a lot of energy so the jammer must first detect the Laser pulse to know when to turn on the power and frequently reacts too late to be effective. The first, used by our competitors, is to simply try to overpower the unit by broadcasting a very large amount of infrared light. There are two methods that are used to try to interfere with the accurate reading of speed by LIDAR. Click on the Laser Scrambling Technology tab to see what else we can do. The computer then samples the data to develop an accurate measurement of speed for the target.ĭon't worry, you don't need to understand all of that.we do. Of course, there is always the chance for interference so modern LIDAR contains a computer and sends out multiple pulses for each target measurement…often as many as 50 pulses. Since the LIDAR knows when the pulses go out and measures the distance for each pulse it has all the information it needs to determine target speed. If pulse one distance is D1 and second pulse is D2 and the LIDAR sends out the second pulse T1 seconds after the first then the objects speed can be calculated as the change of distance over time or (D1-D2)/T1. If the LIDAR then sends out a second pulse and measures that distance it can determine if the target is moving and what its speed is. Taking this time and multiplying it by the speed of light gives one the round trip distance. The unit sends out a pulse of infrared light and measures how long it takes to strike an object and return. Police LIDAR (Laser Radar) is a distance measuring device.
