Description
The two-tiered BMD System consists of the PAD, which will intercept missiles at
exo-atmospheric altitudes of 50–80 km (31–50 mi) and the AAD missile for interception at
endo-atmospheric altitudes of up to 30 km (19 mi). The deployed system would consist of many launch vehicles,
radars, Launch Control Centres (LCC) and the Mission Control Centre (MCC). All these are geographically distributed and connected by a secure communication network.
The MCC is the software intensive system of the ballistic missile defence system. It receives information from various sources such as radars and
satellites which is then processed by ten computers which run simultaneously. The MCC is connected to all other elements of the defence through a
WAN. MCC performs target classification, target assignment and kill assessment. It also acts as a decision support system for the commander. It can also decide the number of interceptors required for the target for an assured kill probability.After performing all these functions, the MCC assigns the target to the LCC of a launch battery. The LCC starts computing the time to launch the interceptor based upon information received from a radar based on the speed, altitude and flight path of the target. LCC prepares the missile for launch in real time and carries out ground guidance computation.
After the interceptor is launched, it is provided target information from the radar through a datalink. When the interceptors close onto the target missile, it activates the radar seeker to search for the target missile and guides itself to intercept the target. Multiple PAD and AAD interceptors can be launched against a target for high kill probability.

The
Prithvi Air Defence (PAD) is an anti-ballistic missile developed to intercept incoming ballistic missiles outside the atmosphere (exo-atmospheric). Based on the
Prithvi missile,
PAD is a two-stage missile with a maximum interception altitude of 80 km (50 mi). The first stage is a Solid fuelled motor while the second stage is Liquid fuelled. It has manoeuvre thrusters which can generate a lateral acceleration of more than 5
gs at 50 km (31 mi) altitude. Guidance is provided by an intertial navigation system with mid-course updates from LRTR and active radar homing in the terminal phase. PAD has capability to engage the 300 to 2,000 km (190 to 1,240 mi) class of ballistic missiles at a speed of Mach 5.
LRTR is the target acquisition and fire control radar for the PAD missile. It is an active phased array radar having capability to track 200 targets at a range of 600 km (370 mi). The PAD missile has also been called
Pradyumna.
Further development led to the improvement of the interception range from 50 to 80 km (31 to 50 mi). The improved missile will utilise a gimbaled directional warhead, a technology also used by Israel, the US and Russia. This technology allows for a smaller warhead to destroy the target missile.
Prithvi Air Defence Exercise[edit]
The PADE (Prithvi Air Defence Exercise) was conducted on November 2006 in which a PAD missile successfully intercepted a modified
Prithvi-II Missile at an altitude of 50 km (31 mi). The Prithvi-II
ballistic missile was modified successfully to mimic the trajectory of
M-11 missiles.
DRDO plans to test the anti-ballistic shield against missiles with a range of 1,500 km (930 mi). The test will be conducted with a modified Prithvi missile launched from a naval ship and the anti-ballistic missile launched from
Wheeler Island.
The interception of the target missile will take place at approximately 80 km (50 mi) altitude.
On 6 March 2009 DRDO carried out a second successful test of the PAD interceptor missile. The target used was ship launched Dhanush missile which followed the trajectory of a missile with range of a 1,500 km (930 mi).
The target was tracked by Swordfish (LRTR) radar and destroyed by the PAD at 75 km (47 mi) altitude.
On 6 March 2011 DRDO successfully test-fired interceptor missile from Advanced Air Defence (AAD) which destroyed a 'hostile' target ballistic missile, a modified Prithvi, at an altitude of 16 km over the Bay of Bengal. Advanced Air Defence (AAD) missile positioned at Wheeler Island, about 70 km across sea from Chandipur, received signals from tracking radars installed along the coastline and travelled through the sky at a speed of 4.5 Mach to destroy it.

so OP
@RisingShiningSuperpower as per the source no indian
AAD or PAD in concieved or made or tested can engage a enemy missile beyond 100KM altitude how on earth did it
fail at 120Km altitude
