PROXIMITY FUZE 76.2
DESCRIPTION
Designed for use in combination with ammunition of 76.2/59 Naval Guns to counter air attacks and low flying missile attacks.

Capable of multi-role functions without any mode selection devices.

Use of advanced micro electronics techniques enables the product to optimise its performance on targets flying upto 5 metres above sea level.

Sea Clutter Rejection Circuits incorporated for engaging sea skimmers at a few metres above the sea surface.
PRINCIPLE OF OPERATION
Working on the CW Radar Principle, the fuze transmits and receives electro-magnetic waves in course of flight. The detected Doppler signals due to target reflections are processed in a sophisticated electronic unit. This enables the fuze to function in proximity of the target and ensures lethality potential of shell.
FUNCTIONAL MODE
ANTI-AIRCRAFT MODE
Proximity mode intended to function against aircrafts within a passing distance of 5 metres, irrespective of target height.
ANTI-MISSILE MODE
Proximity function against low flying sea skimming missiles- at a height of 5 metres above sea level- within a passing distance of 3 metres.
SELF-DESTRUCTION MODE
Precision Electronic Timer ensures self detonation of the fuze between 21 and 31 seconds of time of flight.
NGS MODE
Intended for long range application against the Naval Ground Support requirement.
IMPACT BACK-UP
Proximity mode is backed up by impact function
