NEW DELHI, Jan 18: An indigenously built anti-ship missile defence system to track an incoming missile quickly has been developed by scientists at Institute of Armament Technology, Pune.The new technology does not have the drawbacks of the conventional system which makes detection of sea skimming missiles difficult because of sea water and its mist that affects the propagation of electro-magnetic waves.
In the defence sector, where stakes are always very high, the new system can save valuable seconds with more precision, researchers said at a recently-held international conference on cognitive systems here. The new technology is based on `neuro-fuzzy' computer logic which improves the prophetic qualities of a computer by `learning from experience'.
Apart from the sea water, conventional radars also face difficulties in locating a target at short range and when it is close to the surface. The infra-red sensor of the new system is able to search the beacons arising from incoming missile in spite of the
radiation noises emanating from sun and other natural objects.
Once a detection is complete, it directs the radar to orient itself in proper azimuth to determine the range and velocity of the missile.
The interval between infra-red detection and radar's extraction of range and velocity of the target is in the order of milli-seconds, so even highly manoeuvering missiles cannot be missed.
