PURPOSE: To obtain a decoy effective for a missile having a double mode seeker, by integrally constituting a high frequency generator and an infrared ray generator as the decoy for the missile.

CONSTITUTION: A decoy for a missile is constituted of controllers 1, 2 and a high frequency/infrared ray decoy dispenser 3 and high frequency/infrared ray simultaneous generators 4 are received in the dispenser 3. When the decoy disposal of the controller 1 is indicated, the controller 2 accepts said indication to throw away one or plural generators 4 of the dispenser 3. Each of the generators 4 is integrally constituted of a high frequency generator and an infrared ray generator and the decoy effective for the missile having a double mode seeker is obtained.
