HIZIR Torpedo Countermeasure System is
a state-of-the-art torpedo countermeasure system designed for surface ships.
HIZIR basically detects, classifies and localizes
the threat torpedoes and advises the appropriate countermeasure tactics to
escape from the threat torpedoes.
HIZIR System comprises; Towed Array, Towed Decoy, Winch, Electronic Cabinet, Launchers, Expendable Decoys, Display/Control Units (Consoles)
Towed Array has triplet
hydrophone structure with advanced detection, classification and localization
algorithms that immediately resolve left-right ambiguity of incoming torpedo
threats without requiring the ship to maneuver.
Once a torpedo is detected, the
system advices to the operator the most appropriate tactic for evading the
torpedo threat. These tactics include the evasive maneuver of the ship, the operational
parameters of towed decoy and the deployment pattern of expandable decoys.
Towed Decoy is a programmable
unit that emits wideband acoustic noise to mask own-ship noise. On the other
hand, expendable decoys emits wideband noise to cut the engagement of the
torpedo and emulates acoustic characteristics of own-ship to attract the torpedo
in jammer and decoy mode, respectively.
