IIT is helping Army crack its biggest puzzle - tunnels

On November 30, 2016, a day after the Samba attack, the BSF discovered a cross-border tunnel, which it believed terrorists used to infiltrate.

In July 2012, four years before the Pathankot attacks, the army had discovered a 20-ft deep tunnel with a complete ventilation and breathing system 340 metres inside India from the International Border (IB) in Samba sector, only 58-km from the Pathankot air base.

The Centre is looking to expedite its hunt for two key technologies— tunnel detection and gunshot detection systems— that it hopes will help prevent such activity.

The National Centre for Excellence in Technology for Internal Security (NCETIS) at IIT-B, which also has people working with other IITs, has developed a Ground Penetrating Radar (GPR) at 920MHz, which can not only detect tunnels but also landmines buried in soil.

"Right now, we testing the equipment for ruggedness. We have a mandate that it needs to work in all terrains and conditions and once the ruggedness test is complete, we will begin the field trials in February," Seema Periwal, project manager, NCETIS told TOI from Mumbai.

The MHA issued a notice earlier this month inviting vendors, manufacturers, distributors and experts to share their views, suggestions and even product details with it.

Sources in the MHA also said that India is looking at a technology from Israel.

What is gunshot detection?
While tunnel detection is one aspect, the BSF is also looking at equipping itself with a three-tier gunshot detection system—which can provide an alert 1 second after a enemy shot has been fired in the range of 300 metres to 1,200 metres.

It finalised the QRs for three systems last year: Standalone detection system, vehicle mounted system and weapon mounted system, which can be deployed to protect buildings or camps, used during patrolling and on-ground fighting scenario.

The system can detect different types of weapons.

For a 5.56mm weapon, BSF has asked for a detection range of at least 300, while the same is 400m for a 7.62x39mm weapon, 500m for a 7.62x5.1mm weapon and 1,200m for a 12.7mm weapon.

Sources said that the MHA is likely to look outside of India for this technology, although no final decision on it has been taken.
