Q

It is reported that the RADAR is not receiving small targets. The most likely causes are:

🔍 Key Concepts

• RADAR receiver sensitivity and which components most affect it • Difference between transmitter-side issues (magnetron, PFN) and receiver-side issues (IF amplifier, local oscillator, tuning) • How power supply or blown fuses generally affect the entire set vs. only small targets

💭 Think About

• Which components would cause ALL targets to disappear, and which would mainly reduce sensitivity so that only small/weak echoes are lost first? • Look at each answer choice: which groups of components logically go together as affecting detection of weak signals at the receiver stage? • Think about where in the RADAR chain small, low-energy echoes are most likely to be lost: transmission, reception, intermediate frequency amplification, or display/processing?

✅ Before You Answer

• Identify which listed components are mainly transmitter high‑power parts vs. low‑level receiver parts • Ask whether a problem with a given component would usually affect all targets or selectively hurt weak/small targets first • Confirm that the components in the best choice all relate to receiver sensitivity and tuning, not general power or digital processing failures
