🔍 Key Concepts

• Purpose of the I.F. (Intermediate Frequency) amplifier in a radar receiver • Relationship between receiver bandwidth, noise, and detection of weak (long‑range) echoes • How range settings affect required signal selectivity and clutter rejection

💭 Think About

• Think about whether weak, long‑range radar echoes need more protection from noise (narrower or wider bandwidth?) compared to strong, short‑range echoes. • Consider how changing the radar range scale affects the type of signals you want to accept or reject in the receiver. • Ask yourself: does the radar normally change the electronic bandwidth automatically with range, or is it fixed by design?

✅ Before You Answer

• Verify how bandwidth affects noise level and signal-to-noise ratio in a receiver. • Check whether typical marine radar I.F. stages are designed with a fixed intermediate frequency and bandwidth or one that tracks range scale. • Confirm if normal radar controls available to the operator (gain, sea clutter, rain clutter, tuning) include a direct bandwidth adjustment.
