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.
