Correct Answers and Explanations

Question 1

Correct Answer: C) Electronic Support (ES)
Explanation: Using passive sensors to detect enemy radio transmissions without transmitting is an Electronic Support (ES) activity, focused on intelligence gathering.

  • A) Electronic Attack (EA): Incorrect, as EA involves active disruption, not passive detection.

  • B) Electronic Protection (EP): Incorrect, as EP protects systems, not detects signals.

  • D) Signal Jamming: Incorrect, as jamming actively disrupts signals, not passively detects them.

Question 2

Correct Answer: B) Jamming
Explanation: Transmitting interference to disrupt drone control signals is jamming, an Electronic Attack (EA) technique.

  • A) Spoofing: Incorrect, as spoofing sends false signals to deceive, not disrupt.

  • C) Signal Amplification: Incorrect, as amplification strengthens signals, not interferes with them.

  • D) Frequency Hopping: Incorrect, as this is a protective measure, not an attack.

Question 3

Correct Answer: A) Deception
Explanation: Sending false radar signals to misrepresent an object’s position is a deception technique, aiming to mislead the enemy.

  • B) Signal Boosting: Incorrect, as boosting increases signal strength, not creates false signals.

  • C) Jamming: Incorrect, as jamming overwhelms radar, not mimics signals.

  • D) Encryption: Incorrect, as encryption secures data, not manipulates radar.

Question 4

Correct Answer: A) Low Probability of Intercept (LPI)
Explanation: Low-power transmissions reduce the chance of enemy detection, a technique known as Low Probability of Intercept (LPI).

  • B) Signal Jamming: Incorrect, as jamming disrupts signals, not hides them.

  • C) Spoofing: Incorrect, as spoofing sends false signals, not reduces detectability.

  • D) Frequency Modulation: Incorrect, as this adjusts signal properties, not power levels.

Question 5

Correct Answer: B) Flare
Explanation: Flares are used to confuse infrared-guided missiles by emitting heat signatures, a common countermeasure.

  • A) Chaff: Incorrect, as chaff counters radar-guided threats, not infrared.

  • C) Jamming: Incorrect, as jamming uses electronic signals, not physical decoys.

  • D) Stealth Technology: Incorrect, as stealth reduces detectability, not counters missiles.

Question 6

Correct Answer: B) Electronic Protection (EP)
Explanation: Varying a radar’s signal pattern to reduce detection vulnerability is an Electronic Protection (EP) measure.

  • A) Signal Interception: Incorrect, as interception is passive and does not protect systems.

  • C) Electronic Attack (EA): Incorrect, as EA disrupts enemy systems, not protects own systems.

  • D) Deception: Incorrect, as deception misleads enemies, not protects radar.

Question 7

Correct Answer: A) Electronic Support (ES)
Explanation: Detecting and classifying enemy radar signals for threat assessment is an Electronic Support (ES) function.

  • B) Electronic Attack (EA): Incorrect, as EA involves active disruption, not signal analysis.

  • D) Signal Boosting: Incorrect, as boosting strengthens signals, not creates decoys.

Question 11

Correct Answer: A) Burst Transmission
Explanation: Transmitting signals in short bursts to avoid detection is called burst transmission, a protective technique.
