EW SYSTEC

Question 1

Define Electronic Warfare

Answer 1

Any military action whose objective is to exploit the Electro-Magnetic spectrum

Question 2

Explain the role of Electronic Warfare

3 Points

Answer 2

• to improve situational awareness
• reduce attrition of own forces
• defeat the enemies EW attempts

Question 3

What are the two classes of jamming

Answer 3

Deliberate – Electronic Jamming, Electronic Neutralisation, Communications Jamming
Non-Deliberate – Mutual Interference, environmental conditions

Question 4

Define Spot Jamming

Answer 4

a jammer focuses all its power on a single frequency, jamming only that specific channel or frequency

Question 5

Define Sweep Jamming

Answer 5

jammer’s full power is rapidly shifted from one frequency to another, effectively jamming multiple frequencies in quick succession, though not simultaneously.

Question 6

What is the difference between Spot and Sweep jamming?

Answer 6

Spot jamming - Jammer focuses its power on a single frequency.
Sweep jamming - Jammer shifts its full power across a range of frequencies

Question 7

Define Barrage Jamming

Answer 7

using a wide noise bandwidth to cover several radars with one jammer compensate for any uncertainty in the radar frequency

Question 8

What is RADAR Burn through

Answer 8

the distance from a radar at which jamming becomes ineffective, allowing the radar to receive a strong enough target signal to track it.

Question 9

What is frequency agility?

Answer 9

the radar or communication system rapidly changes its operating frequency to avoid interference, jamming, or to improve detection
