What happens when you lower the range setting on the RADAR?

Lowering the range setting on the radar effectively narrows the radar's field of view, allowing it to focus on a smaller area in front of it. This action results in the radar responding primarily to nearby objects, which typically have stronger signals. When the range is set to a lower value, the radar system is optimized to detect closer vehicles or objects that are emitting a stronger radar return, making it easier to track them accurately.

By focusing on these closer, stronger signals, the radar becomes better at distinguishing the relevant traffic in its immediate vicinity, improving situational awareness for the operator. This functionality is essential in situations where precise speed measurements of nearby vehicles are necessary, such as in radar enforcement on highways or urban areas.

In contrast, increasing the range setting would enable the radar to detect signals from further away, but would also include weaker signals, making it less effective at pinpointing nearby vehicles. Thus, option B accurately describes the consequence of lowering the range setting.
