What Is Electronic Warfare (EW)? Invisible Combat Explained

# What Is Electronic Warfare (EW)? Invisible Combat Explained
Quick answer: Electronic warfare (EW) is the use of radio waves and electromagnetic signals to attack, defend against, or detect enemy electronics — radars, communications, missiles, GPS, and drones. EW is invisible to the eye but can decide modern battles. A blinded radar can’t shoot, a confused missile can’t hit, a jammed army can’t talk.
The Three Branches of EW
| Branch | Acronym | What It Does |
|---|---|---|
| Electronic Attack | EA | Jam, spoof, deceive enemy electronics |
| Electronic Protection | EP | Defend own electronics from enemy EW |
| Electronic Support | ES | Listen to enemy emissions, locate them |
All three work together in modern operations.
Electronic Attack (EA) — Offense
Jamming
Flood enemy radar frequencies with noise so it can’t see anything. Like shining a flashlight into someone’s eyes.
Types:
- Barrage jamming — wide-band, low-power
- Spot jamming — narrow, high-power on specific frequency
- Sweep jamming — moves across bands
- Smart noise jamming — modulated to look like real targets
Spoofing
Send fake signals that look real but lead enemy missiles or sensors to wrong places.
Examples:
- GPS spoofing — make drone think it’s somewhere else
- Radar spoofing — create fake target echoes
- Comms spoofing — fake friendly orders
Deception
Use decoys — chaff (radar), flares (IR), and drones to fool missiles.
Electronic Protection (EP) — Defense
How your own electronics survive EW:
- Frequency hopping — change frequency 1000+ times/sec
- Spread spectrum — spread signal over wide band
- Encryption — even if intercepted, content is hidden
- LPI/LPD radar — Low Probability of Intercept/Detection
- Anti-jam GPS antennas (CRPA)
- Radio silence when possible
The F-35’s LPI radar can search the sky without enemy RWR even knowing.
Electronic Support (ES) — Listening
Identify and locate enemy emitters:
- ELINT (Electronic Intelligence) — analyze enemy radars
- SIGINT (Signals Intelligence) — intercept enemy comms
- DF (Direction Finding) — locate the transmitter
- TDOA / FDOA — time-difference/frequency-difference to triangulate
Specialized aircraft like the EP-3 Aries, RC-135 Rivet Joint, and Beriev A-50 are flying ELINT platforms.

EW in Recent Wars
2020+ Karabakh
Azerbaijani KORAL EW jammed Armenian radars and drones, paving the way for TB2 strikes.
2022+ Ukraine
- Russian Krasukha-4 jammed Ukrainian comms and air defense radars early
- Ukrainian commercial drones often crashed due to Russian Pole-21 GPS jamming
- US-supplied Excalibur GPS-guided shells lost accuracy until counters developed
- Both sides used EW intensively — sometimes called the “first major electronic war”
2024+ Middle East
- Iran reportedly used GPS spoofing extensively
- Israel used EW heavily in Lebanon and Iran operations
- Houthi drones encountered NATO EW (Eilat, Red Sea)
GPS Jamming and Spoofing
Modern weapons rely on GPS. EW counters:
- GPS jamming — flood the GPS frequency with noise (cheap)
- GPS spoofing — broadcast fake GPS that looks real (sophisticated)
In 2018, North Korean GPS jamming briefly affected South Korean civilian flights.
In Ukraine, Russian GPS jamming forced US to upgrade JDAM-ER bombs with more anti-jam GPS receivers.
Why EW Matters in Drone Wars
Most drones rely on:
- GPS for navigation
- Radio control link to operator
- Optical seeker for final approach
EW can defeat all three:
- Jam GPS → drone gets lost
- Jam radio → operator loses control
- Spoof GPS → drone lands where defender wants
This is why EW is now a cheap, scalable counter to drone swarms — far cheaper than missiles.
DRFM — The Modern EW Heart
Digital Radio Frequency Memory (DRFM) is the brain of modern EW. It can:
- Record an enemy radar pulse
- Modify it (shift in time, frequency, phase)
- Retransmit so the enemy radar sees fake targets
Modern EW pods like Next-Gen Jammer (NGJ) use DRFM extensively.
Quantum and AI in EW
Emerging tech:
- AI-driven cognitive EW — adapts in real-time to enemy frequencies
- Quantum radar — theoretically immune to traditional EW (still experimental)
- Software-defined radio (SDR) — fast frequency hopping
- Cyber-EW fusion — attack enemy systems through their electronics
A Kid-Friendly Analogy
Imagine a soccer game where players communicate by walkie-talkies. Now imagine one team starts:
- Jamming — playing loud music on opponents’ radios
- Spoofing — pretending to be the opponent’s coach giving fake orders
- Listening — secretly hearing the opponent’s strategy
That’s electronic warfare. The team that controls the airwaves usually controls the game.
A Brief EW History
- WWII — first major EW: British “Window” (chaff) and German radar jamming
- Vietnam — extensive EW vs SA-2 SAMs (F-105 Wild Weasels)
- 1973 Yom Kippur — Israeli EW failure cost many aircraft to SAMs
- 1991 Gulf War — US dominance via EF-111, EA-6B
- 1999 Kosovo — F-117 shot down due to inadequate EW
- 2014+ Ukraine (Donbas) — Russian EW shocked Ukrainian forces
- 2022+ Ukraine (full-scale) — most intensive EW war in history
The Türkiye EW Story — KORAL
The KORAL electronic warfare system (Aselsan) became famous in Operation Olive Branch (Afrin, 2018) and Operation Peace Spring (Syria, 2019). It reportedly jammed Russian-made radars effectively.
KORAL operates in long range (150+ km), targeting enemy radars while staying outside their reach. Türkiye continues building advanced EW including SANCAK (comms), GERGEDAN (anti-drone), and aircraft-mounted EW for Akıncı, ANKA-3, and KAAN.
