🔍 Key Concepts

• AGC (Automatic Gain Control) and IAGC (Instantaneous Automatic Gain Control) functions in a marine RADAR receiver • Typical dynamic range or gain-control range needed to deal with very weak and very strong echoes • Which dB ranges in the options are large enough to handle sea clutter, rain clutter, and strong nearby targets

💭 Think About

• Think about the range of echo strengths a radar receiver must handle: from small, distant targets to large ships and land close by. Would that require a small, medium, or fairly wide gain-control range? • Compare each option: which one would be unrealistically narrow for practical RADAR use, and which ones seem more in line with how much the receiver must be able to increase or decrease gain? • Consider that AGC/IAGC must reduce gain significantly in heavy clutter and increase it for weak targets; which range best matches that role?

✅ Before You Answer

• Eliminate any dB ranges that seem too small to be useful in real-world clutter conditions • Focus on the answer that represents a substantial but realistic dynamic range (not just a tiny adjustment) • Make sure the chosen range could realistically cover both strong close-in echoes and weak distant echoes without saturating the receiver
