What is an essential benefit of maintaining a distance between radar units?

Maintaining a distance between radar units is essential primarily because it ensures precise measurement by reducing signal overlap. When radar units are positioned too closely to one another, their signals can interfere with each other, which can lead to inaccurate speed readings or difficulties in distinguishing which radar unit has captured the speed of a target vehicle. This overlap may confuse the system and potentially result in erroneous data, making it harder to determine the accurate speed of the vehicles being monitored. By spacing the units adequately apart, officers can enhance the reliability and accuracy of the measurements taken, leading to more effective speed enforcement and better overall data integrity. This practice helps in ensuring that each radar system can operate independently and effectively, thus improving overall enforcement efforts.
