There are some limitations and systemic errors with radar gun technology that have not been completely addressed with updates and changes to newer models of radar guns.
Electromagnetic interference can occur at lower frequency signals. As radar guns have evolved, much effort has been taken to continue to increase the frequencies of signals used. Innovations include changing the signal from radio wave signals to a higher frequency and changing them to much smaller wavelength, microwave, or infrared signals. Additionally, a narrower beam reduces the chance of obtaining false readings from nearby objects or other vehicles. These shadowing errors have also been addressed by using other forms of speed measurement, such as laser or light detection and ranging technology (LIDAR). While the fundamental distance and speed measurement premise is much the same, the use of the narrower laser light beam to measure the speed of a vehicle can better measure the speed of an individual vehicle within a stream of traffic than radar technologies can.
Radar and LIDAR technologies are also affected by physical and mechanical limitations. A clear line of sight is always necessary to make measurements. The greater the distance and angle of measurement, the greater the error and more likely the reading taken is not the actual speed of the moving vehicle. Lastly, as with all mechanical devices, there will always be levels of uncertainty, unusual behavior, and failures.
