🔍 Key Concepts

• Superheterodyne receiver architecture in marine RADAR • The role of a mixer in changing signal frequency for easier processing • Difference between modulating a transmitter and frequency conversion in the receiver

💭 Think About

• In a typical RADAR receiver chain, where is the mixer located: in the transmitter section, receiver section, or antenna system? • Does the mixer primarily change the pulse shape, block signals, or shift a signal from one frequency band to another for amplification/detection? • Which choice best matches the idea of taking an incoming RF echo and moving it to an intermediate frequency (IF) for processing?

✅ Before You Answer

• Identify which option describes frequency conversion rather than modulation of audio or pulse formation. • Eliminate any option that talks about preventing signals or forming pulses, as that is usually done by other circuits (modulator, T/R switch, pulse-forming network). • Confirm that the correct function of a mixer is tied to creating an intermediate frequency (IF) from two different input frequencies.
