Abstract (en)
A decoy comprises a parachute 1 which, in use, suspends a support column 2 from which hangs a thread 3 comprising multiple antenna array elements 4 and a power pack 6. The decoy has been released from containment in a separable casing 5a, 5b. The casing is launched into the air by a launcher (not shown). Each antenna array element comprises multiple conjugate antenna pairs in an array, each antenna pair connected by a transmission line, all transmission lines being of equal length and the antenna arranged equi-distantly about a centre of the array, and an amplifier associated with each transmission line.
