Radio, Radar, and Sonar Systems Quiz

What is the primary function of a transponder in the context of radio, radar, or sonar systems?

• To amplify incoming signals

• To automatically transmit a signal upon reception of a designated incoming signal

• To decode encrypted signals

• To store data from incoming signals

Which type of radar requires the use of an active sensor computer to identify an object?

• Primary Surveillance Radar (PSR)

• Secondary Surveillance Radar (SSR)

• Passive radar

• Active radar

What is a distinguishing feature of Primary Surveillance Radar (PSR)?

• It requires a reply from the aircraft.

• It operates by transmitting a narrow beam of RF.

• It can get barometric altitude and identification information.

• It uses encrypted signals for detection.

How does Secondary Surveillance Radar (SSR) differ from Primary Surveillance Radar (PSR) in terms of aircraft response?

• SSR does not require a reply from the aircraft.

• SSR and PSR both require replies from the aircraft.

• SSR requires a reply from the aircraft.

• Neither SSR nor PSR requires a reply from the aircraft.

What is the primary purpose of the Air Traffic Control Radar Beacon System (ATCRBS)?

• To control air traffic manually

• To provide weather updates

• To combine PSR and SSR systems for a total range of information

• To monitor ground traffic

What does the ATCRBS use to allow continuous communication between its system and aircraft?

• Single frequency operation

• Two different frequencies

• Multiple antennas

• Only PSR systems

Which component of the ATCRBS is responsible for determining the validity of incoming signals?

• Transmitter

• Modulator

• Decoder

• Receiver

What type of signal does the ATCRBS encoder generate?

• DC pulse

• RF pulse train

• Reply signal

• Control signal

What information does the airborne transponder provide to the radar operator when working with a ground radar system?

• Weather conditions

• Aircraft security information

• Engine performance

• Navigation routes

What is the purpose of Mode 1 in the Air Traffic Control Radar Beacon System (ATCRBS)?

• Barometric altitude identification

• Traffic identification

• Security identification/Mission Number

• Personal identification
