🔍 Key Concepts

• Basic block diagram of a marine RADAR system (transmitter, receiver, antenna, indicator, power supply, and timing/control unit) • How the timing of transmitted pulses and screen sweep must be synchronized for accurate range display • Which component in RADAR is specifically responsible for generating and distributing timing pulses

💭 Think About

• Think about which part of the RADAR must control when each pulse is transmitted and when the receiver is allowed to listen for echoes • Consider how the RADAR display sweep knows when to start each new trace in step with the transmitted pulse • Ask yourself which components main function is timing and coordination rather than power, display, or signal amplification

✅ Before You Answer

• Identify the component whose primary job is to create and send timing signals to other sections • Eliminate components that mainly supply energy or display information rather than control timing • Confirm which unit in standard RADAR diagrams is often linked to both the transmitter and the indicator to keep them in step
