Interceptor spot on, though without blast: DRDO
Scientists say Prithvi Defence Vehicle mission achieved important objectives
India's ambitious mission on Sunday to intercept an "enemy" ballistic missile at a altitude of 120 km seems to have achieved only partial success
. While the missile technologists of the Defence Research and Development Organisation (DRDO) say the interception did take place and the mission met its "important objectives," they concede that the warhead in the interceptor missile, which took off from the Wheeler Island,did not explode.
Avinash Chander, Scientific Adviser to the Defence Minister, said: "The infrared (IR) seeker in the interceptor could track the target, but we have not exploded the target. The target was not to be exploded.
Asked if the mission was only "partially successful," Mr. Chander, architect of India's Agni series of missiles, said, "The mission's main objective was to track the target missile. We wanted to see the performance of the IR seeker. The warhead in the interceptor missile was not meant to be exploded in this mission. Since we did not fire the warhead, the debris did not fall."
Another DRDO missile technologist said: "We have recorded the interception."
Asked whether "a hit-to-kill" took place in the mission as it did in the previous six other interceptor flights from the Wheeler Island, he said: "We have to work out the missed distance between the target missile and the interceptor. Based on that, the hit-to-kill would take place. We arenotable to say right now whether the hit-to-kill took place."
Yet another scientist said, "Whether the target missile was destroyed or not, I cannot say right now."


.The DRDO was looking forward to this mission because it was "challenging" and "complex." Of the DRDO's seven interceptor missions, six were successful. The interceptions had taken place either in the endo-atmosphere (below 50 km) or in the exo-atmosphere (between 50 km and 80 km). But this mission was a different ball game because the interception was to be done at 120 km, providing very little time for the interceptor to blast off and waylay the attacker. So the motors in the interceptor called the Prithvi Defence Vehicle (PDV) and the target missile were specially developed. The target missile lifted off a ship in the Bay of Bengal, off Odisha at 9.07 a.m. It was a two-stage missile, "mimicking a hostile ballistic missile approaching from more than 2,000 km away," a DRDO press release said.
In an automated operation, radar-based systems on the Wheeler Island and in Paradip, Puri and Cuttack detected and tracked the "enemy" missile. The computer network, with the help of data from the radars, predicted its trajectory. The single-stage PDV interceptor took off two-and-a-half minutes later.
The PDV, guided by the highly accurate inertial navigation system and supported by a redundant micro-navigation system, moved towards the point of interception. Once the PDV crossed the atmosphere, its heat shield domes covering the IR and radio frequency (RF) seekers fell off. So the two seeker domes opened to look at the incoming missile's location. With the help of inertial guidance and the IR seeker, the PDV moved for the interception. "The mission was completed and the interception parameters were achieved," the press release said.
G. Satheesh Reddy, Director, Research Centre, Imarat , a DRDO missile facility in Hyderabad, said the mission featured several new technologies. Both the missiles had new, powerful motors. The heat shield, covering the IR and RF seekers, ejected for the first time. The seekers worked well. "This is the first time that an imaging seeker has been used for the air defence vehicle. The imaging seeker could see the incoming missile, track it and guide the interceptor towards the target." The RCI team made the seekers and the inertial navigation and guidance system, Mr. Reddy said.
Adalat Ali was the Programme Director and Y. Sreenivasa Rao, Project Director.

Hain?? If its hit to kill why do we need an explosion? The kinetic energy knocks off the enemy missile.

PAD, AAD,PDV ,none of them is for kinetic energy killing---'hit to kill' like American's BMD missiles but exploded warhead...

1. PAD 's 30 kg explosive warhead is well reported
2. As a deep further improvement varient of PAD...it will be more reasonable for PDV with the same warhead
3. AAD is claimed as ' hit to kill' by the Indian Media only due to lack of necessary knowledge and wiseacre. indian media misexplain ' interception' as 'hit to kill' in their reports...but if you go back to the source : DRDO's official statement, you would know the fact.

here is the one for the AAD test on Nov 23rd 2012...we can read.

The Ring Laser Gyro based Navigation System in Target, Fibre Optic Gyro based INS in Interceptor, Onboard computers, Guidance systems, Actuation Systems and the critical RF Seekers used for the terminal phase have performed excellently. The AAD Missile system initially guided by Inertial Navigation system was continuously getting update of the target position by the Radar through a data link. The Radio Frequency (RF) seeker tracked the Missile & Onboard computer guided the Missile towards the Target Missile and hit the target.

The Radio Proximity Fuse (RPF) exploded the warhead thereby destroying the target missile completely.

Wait a minute? If "hit-to-kill" technology was adopted in this test, why they need to work out the distance between the target and interceptor? Hit, then kill; no hit the no kill, simple as that!
Secondly, the observation system can't give the real time data in this test? Then how your interceptor track the target?
