Siren is an active jammer deployed from standard RBOC decoy launcher on board the surface ships. The reaction time of the decoy is 7 seconds, which are required for the downloading of the threat’s identification profile, flying a rocket assisted trajectory over a distance of 10 miles, where the decoy is suspended under a parachute, and prepares a repertoire of deception and jamming signals tailored for anticipated specific threat. Utilizing a mirror like directional reflector, Siren scans the area for targets and when the target is located, it focuses its transmission at a narrow arc where the incoming threat is detected. Since the decoy is fired remotely from the ship, a home on jam countermeasures will also deviate the missile from its target.
