How can radars be tuned?

• A. Manually
• B. Auto-tuning control
• C. Manually or by auto-tuning control
• D. By range scale adjustment

Answer: (C)

Tuning a radar means adjusting its settings so the system performs at its best under current conditions. You can do this manually, using physical controls or on-screen menus to tweak parameters like receiver gain, filter settings, and processing thresholds for optimal target detection. You can also use auto-tuning control, where the system automatically selects the best settings to compensate for drift, temperature, and clutter. Range scale adjustment, on the other hand, only changes how far out your display shows targets; it doesn’t tune the radar hardware or its signal processing. So the correct answer is that radars can be tuned either manually or by auto-tuning control.
