13R Firefinder Radar Operator Practice Exam

13R FIREFINDER RADAR

OPERATOR PRACTICE

EXAM Question 1: What is the primary mission of the AN/TPQ-36 Fire�nder Radar system?

Choices:

1) To track enemy aircraft and guide surface-to-air missiles.2) To detect and locate enemy mortars, artillery, and rocket launchers for counter-battery �re.3) To provide weather forecasting and atmospheric analysis for �eld artillery units.4) To intercept and jam enemy tactical communications networks.Correct Answer: To detect and locate enemy mortars, artillery, and rocket launchers for counter-battery �re.Explanation: The primary mission of the AN/TPQ-36 Fire�nder Radar is to detect, track, and locate hostile mortar, artillery, and rocket �re positions so that friendly units can execute rapid counter-battery �re.Page 1

Question 2: Which frequency band does the AN/TPQ-36 Fire�nder radar operate within?

Choices:

1) S-band 2) C-band 3) X-band 4) Ku-band

Correct Answer: X-band

Explanation: The AN/TPQ-36 radar system operates within the X-band (at 32 frequencies), which provides the high resolution necessary for accurately tracking smaller projectiles like mortar rounds.

Question 3: What is the standard azimuth scan sector of the AN/TPQ-36 radar

during normal operations?

Choices:

1) 45 degrees 2) 90 degrees 3) 180 degrees 4) 360 degrees

Correct Answer: 90 degrees

Explanation: The AN/TPQ-36 radar electronically steers its beam across a 90-degree sector to scan for incoming hostile projectiles.Page 2

Question 4: Unlike the AN/TPQ-36, the AN/TPQ-37 Fire�nder radar operates primarily in which frequency band to handle longer-range detection?

Choices:

1) S-band 2) X-band 3) L-band 4) Ka-band

Correct Answer: S-band

Explanation: The AN/TPQ-37 operates in the S-band, which su�ers less atmospheric attenuation and allows for signi�cantly longer tracking ranges for heavy artillery and long- range rockets.

Question 5: What is the minimum crew required to perform mobile, continuous 24-

hour operations for an AN/TPQ-37 radar section?

Choices:

1) 2 to 4 personnel 2) 4 to 6 personnel 3) 8 to 12 personnel 4) 15 to 20 personnel

Correct Answer: 8 to 12 personnel

Explanation: Due to the physical size of the system, deployment demands, and continuous shift work, a full crew of 8 to 12 personnel is necessary for sustained 24-hour mobile operations.Page 3
