Defence Research Development Organisation (DRDO) has an impressive range of equipment in its armoury to offer to the Forces battling ambushes from across the border and also attacks by the insurgency groups within the country. A significant chunk of equipment and gizmos developed by the DRDO has been inducted into defence forces and paramilitary forces and in some cases, technology has been transferred for commercial production. Officials said their mass induction perhaps can further aid in tackling such situations but added that terrain and length of the surveillance area play major role in making such decisions.
Senior DRDO officials, speaking to TOI, cited the example of Battle Field Surveillance Radar – Short Range (BFSR-SR) being used by armed forces. “BFSR-SR is a battery-powered, light-weight, man-portable surveillance radar. It can search a specified sector and can simultaneously track multiple targets and carry out doppler based classification of various ground surface targets”, said a DRDO official adding that the radar has a low probability of being intercepted and has the ability to detect, track and classify a crawling man (at a distance of 700 m), single man walking (3 km) and moving heavy vehicles (14 km).
Battle Field Surveillance Radar sets off an audio alarm on detection of new target over fenced area while multiple targets can be simultaneously tracked in Track-while-scan (TWS) mode and is capable of working in all-weather conditions including high-wind speeds. ”
It has made round the clock surveillance of forward areas more effective. The radar is a potential sensor for Border Security Force, Coast Guard and Army. The networked BFSR-SR can provide online situational awareness at control centre”, the officer said.
‘Netra’ is another such DRDO product which is a fully autonomous, light-weight Unmanned Aerial Vehicle developed specifically for counter insurgency operations which require day and night vision facilities for surveillance and reconnaissance. “Equipped with auto -pilot and in-built safety features, it returns to base on communication loss or low battery”, said the official, adding that ‘Netra’ is ideal for deployment and recovery in confined areas of operation.
Another device, which can be a major asset for our soldiers is the Integrated Multi-Function Sight which will soon be made available to the armed forces in thousands. This light-weight and compact device consists of Thermal Imager (TI) and a Laser Range Finder (LRF) and is capable of operating during day and night. “Used for surveillance and speedy engagement of targets by the soldier, this equipment is capable of measuring the target range as well as its own position and can also compute the location co-ordinates of the target,” said the official.
Low Level Light Weight Radar, ‘Bharani’ provides early warning to Army and Air Defence Weapon Systems mainly in mountainous terrain against hostile aerial agents like Unmanned Aerial Vehicles, helicopters and fixed wing aircraft flying at low and medium altitudes. “The radar has ‘Identification of Friend or Foe system that can detect, confirm, classify and attain IFF status on every target in battlefield under surveillance”, the official averred.
