How many amplifiers are in the Primary Surveillance Radar (PSR) transmitter?

• A. 1.
• B. 4.
• C. 8.
• D. 12.

Answer: (C)

In a Primary Surveillance Radar (PSR) system, the transmitter typically consists of several amplifiers to ensure the radar signal is powerful enough to be transmitted over long distances and can effectively return information from targets such as aircraft. In this context, having eight amplifiers in the PSR transmitter is standard for achieving the necessary signal strength and maintaining the reliability of radar operations. Each amplifier serves to boost the signal progressively, allowing it to reach the required power levels for effective detection. This multi-amplifier arrangement is crucial for enhancing the system's performance and ensuring that the radar can operate effectively under various conditions. Understanding this configuration emphasizes the importance of signal amplification in radar technology.
