  1. Decision Supportfor Fighter Pilots Lars Rosenberg Randleff Ph.D. student Danish Defence Research Establishment

  2. Rationale • Numbers of threats, guidance methods, and countermeasures are increasing • 650 missile systems developed • 200-300 missile systems currently deployed (http://missile.index.ne.jp) • Not easy to find the best action • Takes training to do it in time • Solution depends on mission • “The worlds best pilot as the co-pilot” • A work in progress…

  3. Challenges • Lack of information • Both in flight and in development • Information may be self-contradictory • Onboard systems may be wrong • Best solution depends on a lot of parameters • Avionics, route, scenario, inventory, … • Should be found in real-time

  4. Missile Guidance Active Radar Semi-active Radar Infrared Beam Rider Anti-Radiation Command Track-Via-Missile INS/GPS Electro-Optical

  5. Scenario

  6. Parameters α ρ

  7. Lethality Scenario Lethality

  8. Countermeasures • Jammer • Emits RF radiation • Very “loud”, use only when needed • Towed Decoy • A towed jammer • Use once only • Limited resource • Chaff • Forms a cloud with a RCS comparable to that of the aircraft • Limited resource

  9. Reduction of Lethality (α)

  10. Reduction of Lethality (ρ)

  11. An Example • α = 125°ρ = 80% • R = Rα∙Rρ • RJ,α = 0.80RJ,ρ = 0.50RJ= 0.40 • RD,α = 0.75RD,ρ = 0.80RD = 0.45 • RC,α = 0.05RC,ρ = 0.60RC = 0.03

  12. None Jammer Chaff Decoy Highest Reduction

  13. Constraints • The towed decoy can be used a limited number of times (~3) • Chaff can be dispensed a limited number of times (~30) • No countermeasure should be chosen, if none is needed

  14. Building a Mathematical Model

  15. Decision Schedule

  16. Concluding Remarks • Is it better to look ahead? How much? • Can calculations be done fast enough? What should be the timeframe? • Does uncertainty make a difference? • Scenario • Reductions

  17. Credits • Dr. Fred Wright, GTRI • Problem, concept • Mr. Steen Søndergard, DDRE • Models, numbers • Dr. Jesper Larsen, IMM/DTU • Mathematical model
