ATT TEST 3 FINAL PAPER 2026 FULL
QUESTIONS WITH CORRECT ANSWERS
GRADED A+
⩥ 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
