MPH has been a leading innovator in police radar technology for over 38 years. The following information is provided to allow users of our products to learn more about the technology behind police radar, as well as recent developments in traffic radar technology.
General radar technology
The document at this link is a study of the accuracy of MPH’s BEE III radar, FHWA-NJ-2007-022, conducted under a grant from the Federal Highway Administration. It gives an intensive review of the accuracy of the BEE III, demonstrating that it was the most accurate radar tested. Click here.

Distance-measuring police radars
MPH is the only source for distance-measuring (ranging) radars. Ranging technology allows radars to determine exactly which vehicle is being measured by the radar. This overcomes potential vehicle identification errors, especially in fastest vehicle mode. For a visual explanation of how ranging technology helps with target identification, click here.
Ranging technology can also help warn officers of dangerous vehicles (vehicles that do not slow down in response to emergency lights) during a traffic stop. Distance information is critical to avoid false alerts due to distant vehicles, and traffic alerts cannot work reliably without ranging technology.

- The document at this link is a study of speed displays performed by the City of Bellevue, WA at various locations in the City. The study explains how speed displays work and the methodology for deploying them. The study also found that, in their installations, MPH’s Speed Monitor F speed display was reduced traffic speeds 70% more than the other signs studied.

- This document is a summary of the techniques for controlling speeds in school zones, with the associated costs and effectiveness. It shows the benefits of speed signs and trailers, both in effectiveness and cost.
Radar Speed Enforcement Techniques
Rules for operating traffic radar vary from state to state, but the following links may be helpful. Always refer to your own state’s guidelines for specific requirements in your region.
The Michigan Magistrate Adjudication Manual, Unit 6: Traffic Radar provides a good overview of basic radar technology and operating techniques.
