Q

What component of a RADAR receiver is represented by block 46 in Fig. 8A1?

🔍 Key Concepts

• Basic block diagram of a marine RADAR receiver • Function and location of the TR/ATR boxes in relation to the magnetron and waveguide • Where the crystal detector and RF attenuator are usually found in the receiver chain

💭 Think About

• Think about what happens to the transmitted pulse before it reaches the antenna, and what must protect the sensitive receiver front end • Consider where in the chain you would place a component that converts RF (radio frequency) energy into a signal the display can use • Ask yourself which component would most logically be closest to the antenna feed, and which would be deeper inside the receiver

✅ Before You Answer

• Identify whether block 46 is on the transmit side, the receive side, or at the junction between them • Check if block 46 is before or after the mixer/detector stage in the diagram • Confirm whether the function of block 46 is mainly protection, level control (attenuation), or detection/rectification of the RF signal
