Bharat Electronics Limited (BEL), today handed over the first of the 3-dimensional radar ‘Rohini’ to the Indian Air Force. The state-of-the-art Multifunction Medium Range Surveillance Radar has been developed by the Defence Research and Development Organisation’s (DRDO) Electronics and Radar Development Establishment (LRDE), Bangalore and engineered and produced by BEL.
It is capable of handling multiple targets simultaneously and also precisely calculate the height at which projectiles are flying. Mounted on Tatra mobile platform, a heavy duty modified truck built by the public sector Bharat Earth Movers Limited (BEML) and supported by an auxiliary mobile power unit, it enables the Rohini to be easily transported to the battlefront.
Operating in a range of upto 170 kilometres and an altitude of 15 kilometres, the Rohini radar can track multiple targets like fighter jets and missiles travelling at supersonic speeds of over 3,000 kms per hour, viz around Mach 3. The radar employs an array of Electronic Counter Counter Measure (ECCM) features including frequency agility and jammer analysis. A Secondary Surveillance Radar, IFF, is integrated with the primary radar Rohini, which distinguishes friendly and hostile aircraft. About 100 pieces are expected to be built, with around 20 radars being manufactured every year.
The army has conducted successful trials of a Rohini variant for detecting and tracking missiles. Another variant, ‘Revathi’, is being developed for the Navy.
