The Defence Research and Development Organisation (DRDO) has made significant progress in developing next-generation Active Electronically Scanned Array (AESA) radar subsystems designed for deployment across airborne and naval platforms. The initiative marks another step in India’s push to strengthen indigenous defence technology and enhance the operational capabilities of its armed forces.
Unlike conventional mechanically scanned radars, AESA systems employ hundreds or thousands of independently controlled transmit-receive modules that electronically steer radar beams without moving the antenna. This allows the radar to detect, track, and engage multiple targets simultaneously while delivering faster response times and greater reliability in complex combat environments.
The latest development supports India’s broader objective of reducing dependence on imported defence electronics. Indigenous AESA radar technology is expected to play an important role in future fighter aircraft, airborne surveillance platforms, and frontline warships, providing advanced situational awareness and improved resistance against electronic warfare threats.
Modern AESA radars also offer greater operational flexibility through rapid beam steering, enhanced target discrimination, and improved tracking of low-observable aerial threats. Their ability to perform multiple missions-including air surveillance, target tracking, fire control, and electronic support-makes them a critical component of next-generation military platforms.
Over the past two decades, DRDO has steadily expanded its expertise in radar engineering, semiconductor technology, and phased-array antenna design. Continued advancements in these areas are helping India develop sophisticated sensor systems capable of meeting the demands of modern network-centric warfare.
As indigenous radar technologies mature, they are expected to support a wider range of defence platforms while contributing to India’s long-term self-reliance goals under the Atmanirbhar Bharat initiative. Successful integration of advanced AESA systems could also strengthen opportunities for defence exports and reinforce India’s position as an emerging developer of high-end military technologies.
