When adjusting the range control on a RADAR unit, what are we actually adjusting?

Adjusting the range control on a RADAR unit directly affects the sensitivity of the system. The range control determines how far the RADAR can detect targets by setting the minimum and maximum distances that the unit can process effectively. When the range is adjusted, it modifies the thresholds for signal detection, enabling the unit to discern objects at various distances. This is crucial for optimizing performance based on the specific operational requirements and environmental conditions.

The frequency of the RADAR beam is determined by the design of the RADAR system itself and is not affected by the range control settings. Similarly, the angle of the beam is more related to the physical positioning of the antenna and how it is aimed, rather than being something that can be adjusted by the range control. The power output affects how strong the emitted signal is but doesn't directly relate to range adjustment either; it is a separate consideration when configuring a RADAR system. Therefore, the choice of sensitivity is the only one that correctly aligns with the function of the range control.
