What action is referred to when pointing radar at a specific box?

When pointing radar at a specific box, the action referred to is panning. Panning in radar operations involves moving the radar beam from side to side to cover a wider area or to focus on specific targets. This technique helps in tracking the speed of vehicles within a designated area, allowing the operator to establish which vehicles are speeding.

The purpose of panning is to ensure that the radar can effectively identify and track vehicles as they pass through a defined space, providing accurate data for speed detection. This contrasts with other actions such as scanning, which might imply a broader search pattern without a focus, or tracking, which specifically involves following a moving target over time. Meanwhile, measuring typically refers to the process of recording speed data rather than the initial action of directing the radar. Thus, panning is the correct term associated with directing the radar towards a specific area or target box.
