REUSABLE OFF-BOARD MISSILE DECOY
Anti-ship missiles fly at 3-5 m in terminal phase of 10-12 km at speeds upto 3 Mach. The reaction time for Anti-Missile Defense (AMD) is therefore about 10-25 sec. AMD measures include Hard kill measures (physical destruction of the incoming threat through the use of Surface to Air Missiles or Close in Weapon Systems) and Soft kill measures (anti-missile decoys Jamming or Chaff). Modern missiles are designed with ECCM against conventional Chaff & Jamming. Seekers also have ARM home-on features. Active Missile Decoys can impersonate target ship RCS and can be effective as a soft kill AMD measure in terminal phase of the incoming missile. Further decoys can also radiate transmissions such that missiles which passively home on to radiation are also decoyed.
