What is the term used to describe the effect that happens with a two-piece RADAR unit where the antenna and counting box are separated?

The term that describes the effect occurring with a two-piece RADAR unit, where the antenna and the counting box are separated, is known as the panning effect. This phenomenon arises when there is a delay or a discrepancy in the angle of detection due to the physical separation of the components. The antenna is responsible for gathering radar signals while the counting box processes that information. If the vehicle or target moves, the signals detected by the antenna may not immediately correspond with the data being processed, leading to inaccurate speed calculations or tracking.

The panning effect underscores the importance of ensuring that the antenna and counting box are aligned correctly and, if possible, configured in a manner that minimizes any potential lag between them. Understanding this concept is essential for properly utilizing RADAR units in speed enforcement scenarios, as it affects the reliability of the data collected during operation.
