SERVICE DELIVERY QUESTIONS
◉ What are the purpose of RADAR systems?
Answer: Measures VELOCITY and LOCATION of an object by
determining time required for electronic signal to travel to and from
object
◉ What can RADAR detect?
Answer: Position, heading, bearing (azimuth), altitude, speed
◉ What is LOS?
Answer: Line of Sight, line form radar set directly to object
◉ What is range?
Answer: The length of the LOS line
◉ What is the elevation angle (E)?
Answer: Angle between LOS and horizontal plane
,◉ What is the angle measured clockwise from true north in the
horizontal plane?
Answer: True bearing or azimuth
◉ What are 9 parts of a basic radar system?
Answer: Modulator, synchronizer, antenna, antenna control,
transmitter, receiver, display, video processor, duplexer
◉ What part of a radar system controls all radar system timing
signals that ensure synchronous operation and are related to PRF?
Answer: Synchronizer (timer)
◉ What part of radar system contains a pulse forming network
(PFN) that produces high volt pulse to fire transmitter?
Answer: Modulator
◉ What fires the transmitter?
Answer: Pulse Forming Network
◉ What part of radar system produces electromagnetic energy in
the form of continuous waves or short powerful pulses?
Answer: Transmitter
, ◉ What part of radar system is an RF switch that permits radar
system to use a SINGLE antenna to both receive/transmit?
Answer: Duplexer
◉ What part of radar system focuses transmitted EM energy into a
beam, radiates it out into space, and catches the echo signal?
Answer: Antenna
◉ Which part of radar system consists of electromechanical devices
such as synchros, servos, and gyros that correctly position antenna?
Answer: Antenna control
◉ Which part of radar system amplifies and concerts returned RF
echo into video signal?
Answer: Receiver
◉ Which part of radar system analyzes video signal from receiver,
detects inconsistent returns, and shapes signal for clarity?
Answer: Video processor
◉ Which part of radar system uses processed video signals to give
operator visual indication of object info?
Answer: Display
