A smaller angle of the RADAR beam is directly associated with a more focused and narrower detection area, which leads to more accurate speed readings. When the angle of the beam is smaller, the radar device is better able to isolate the target vehicle from surrounding objects or disturbances, allowing for a clearer measurement of its speed. The beam's design essentially allows it to engage with the target in a more direct manner, resulting in readings that are closer to the vehicle's actual speed as it moves towards or away from the radar source.

In contrast, a larger angle can create a wider detection area, which could result in influenced readings due to multiple reflections or interactions with other nearby objects. Thus, when considering the implications of the RADAR beam's angle on measurement fidelity, a smaller angle indeed correlates with a closer approximation to the true speed of the target, enhancing the reliability of the radar's output.
