The term "scope limit" refers to:

The term "scope limit" refers to:

• A. The distance limit of the actual radar equipment shown to the operator.
• B. The maximum number of targets the radar can track simultaneously.
• C. The angular resolution of the radar antenna.
• D. The time it takes for radar to refresh the screen.

Answer: (A)

Scope limit refers to how far out the radar can display targets on the operator’s screen. It represents the maximum range the radar system can present, governed by the equipment’s power, frequency, antenna characteristics, receiver sensitivity, and the display range setting. If a target lies beyond this limit, it won’t appear on the scope even if it’s there. This term is not about how many targets can be tracked simultaneously (that’s track capacity), not about how finely the radar can distinguish targets in angle (angular resolution), and not about how fast the display updates (refresh rate).
