  1. Electronic WarfareCounter-Measures

  2. Electronic Warfare (EW) • Element of Command & Control Warfare (C2W) • C2W includes integrated use of: • Operational Security (OPSEC) • Military Deception • Psychological Operations (PSYOPS) • Physical Destruction • Electronic Warfare (EW)

  3. Importance of EW • Increased reliance on radar • Over-the-horizon targeting • Increased use of Communications • Use of Tactical Data Systems (TDS) • Increased missile & weapons system • Speed • Distance • Accuracy • Necessity for high-speed detection and tracking

  4. Three Components of EW • Electronic Support (ES) *ESM • Electronic Attack (EA)*ECM • Electronic Protection (EP) *ECCM

  5. Electronic Support (ES) • Surveillance of EM spectrum for threat • Detection • Recognition • Warning • Avoidance • Tracking • Targeting • Destruction

  6. ES Receiver Design Requirements • Wide spectrum surveillance • Wide dynamic range • Unwanted signal rejection • Angle-of-Arrival measurement • Signal Analysis capability • Real-Time Display • Recording System

  7. Electronic Attack (EA) • Use of active and passive energy to attack • Personnel • Facilities • Equipment

  8. Non-Destructive EA • Definition: EM energy used to mask or hide real targets by cluttering radar display • Types: • Noise Jamming • Spot Jamming • Barrage Jamming • Sweep Jamming • Flares • Chaff

  9. Effective Jamming PW Rcvd Signal Amp. PRT Ineffective Jamming time

  10. Non-Destructive EA (cont.) • Deception: Create false image or change image on a radar display • Repeaters: Create false image by delaying received radar signals & retransmitting at later time • Transponders: Create false signal by playing back a stored replica of the radar signal • Chaff • Radar Decoys • Blip Enhancers • Radar Cross-Section (RCS) Modification

  11. EA-6B Prowler!!!!!!!!!

  12. Destructive EA • Anti-Radiation Missiles • SLAM • HARM • Sidewinder • Directed Energy

  13. SLAM ER • Stand-off Land Attack Missile-Expanded Response

  14. SLAM

  15. HARM • High-speed Anti-Radiation Missile

  16. HARM Results Portable Serbian Radar

  17. AIM-9 Sidewinder

  18. Electronic Protection (EP) • Protection of friendly combat capability against undesirable effect of friendly or enemy employed EW • Types • Passive EW • Active EW

  19. Electronic Protection (EP) • Three ways to defend from enemy EW • Modify radar • Make it more complex • Make it harder to jam • Modify the Medium • Chaff • Torch • Modify the platform

  20. EP: Radar Design • Power • Frequency • PRF • PW • Pulse Shape • Antenna Design • Scan Pattern

  21. EP Factors • Burnthrough: Increase signal strength to overpower jammer noise (ECCM) • Emission Control (EMCON) • Alpha • Bravo • Charlie • Delta • Operator Recognition Training

  22. U.S. Shipboard EW Capabilities • SLQ-32 “Sidekick” • On all combatants • Radar warning, detection and jamming • Uses internal library to auto detect/categorize • Infrared Flares • On all combatants • Chaff • On all combatants

  23. U.S. Shipboard EW Capabilities • SSQ-108 “Outboard” - • On some DDG, CG, LHA, LHD • Any ship with SSES • Real-time OTH passive detection, localization, and targeting • SLQ-39 Chaff Buoy • On Arleigh Burke class • Rubber Duck • Looks like a life boat container

  24. U.S. Airborne EW Capabilities • ALQ-142 - ES system on SH-60 Seahawk • ALQ-99 - EW system on EA-6B Prowler • ALQ-126 - EA jamming system on F-14 & F/A 18 • ALQ-165 - EA jamming system on F/A-18 • ALR-47 - ES detection system on S-3 Viking • ALR-68 - ES detection system on P-3C Orion • ALR-73 - ES detection system on E-2 Hawkeye • Chaff - On SH-60 Seahawk
