Agra, Dec 28 (IANS) India's first indigenously-developed balloon-mounted radar that will greatly enhance the surveillance capabilities of the armed forces has been successfully launched here, an official said.

The aerostat radar was launched from a military compound and will remain at a height of about one kilometre for the next two or three days. All its systems are working satisfactorily, Sudhir Gupta, the project director, told IANS.

The helium-filled aerostat has night vision cameras and sound recorders, weighs around 300 kg, and can be reused.

Gupta said the aerostat can survey areas upto 20 km away and with avanced cameras, its range can go beyond 100 kms.

At the initiative of the Defence Research and Development Organisation (DRDO), the Agra based Aerial Delivery Research Development Establishment designed and fabricated the high-tech platform.

The aerostat will be used for communication and surveillance. The platform integrates high-end technology, aerodynamics, balloon techniques, hydraulics and high-pressure cylinder technology, according to the scientists involved in the project.

The Indian army and air force hitherto rely on Israeli aerostats that are deployed along the country's western borders but the Indian version would be a cheaper option. They supplement the efforts of the air force's airborne warning and control systems (AWACS) that fly at a much greater height.
