RADAR Principles
What component of a RADAR receiver is represented by block 46 in Fig. 8A1?
-
The ATR box.
-
Correct AnswerThe TR box.
-
The RF Attenuator.
-
The Crystal Detector.
Block 46 in Figure 8A1 represents the Transmit/Receive (TR) switch in a RADAR receiver.
The RADAR receiver consists of various components that process the received signals. In this representation:
"From Waveguide" indicates the input signal received by the receiver.
"46" is the TR switch, which is responsible for directing the signal either to the receiver chain (to be processed for detection) or to the transmitter chain (for transmission).
"Crystal Detector" demodulates the received signal, converting it to an intermediate frequency (IF) signal.
"IF Amplifier" amplifies the IF signal for further processing. "Detector" extracts the modulation information from the IF signal.
"Video Amplifier" amplifies the detected video signal.
"CRT" (Cathode Ray Tube) displays the processed RADAR information.
Mnemonic: "TR - Transit and Receive"

What component of a RADAR receiver is represented by block 47 in Fig. 8A1?
-
The ATR box.
-
The TR box.
-
Correct AnswerThe RF Attenuator.
-
The Crystal Detector.
The signal received from the transmitter (magnetron) must be attenuated before it can be used by the rest of the RADAR System.
Answer C. is the right anser.
