DRDO Unveils India’s First Indigenous Photonic Radar for Advanced Stealth Detection.
Science and Technology
In late June 2025, the Defence Research and Development Organisation (DRDO) announced the development of India’s first photonic radar, marking a major leap in radar technology. The system, currently at Technology Readiness Level 6, integrates photonic components for ultra-high resolution and anti-stealth capabilities ahead of upcoming trials.
- India’s photonic radar uses laser-modulated optical signals—instead of traditional radio waves—to detect objects with superior clarity, sub-millimeter resolution, and reduced electronic interference. It operates across the 100 GHz–THz spectrum, delivering sharper target imaging and improved stealth detection.
- This system is built entirely with indigenous components, such as high-speed optical modulators and fibre-based signal processors, enhancing India’s self-reliance in critical defense technologies. The radar also offers lower detectability, making it difficult for adversaries to intercept using conventional electronic warfare.
Main Point :- (i) DRDO aims to integrate the radar onto stationary platforms, followed by UAVs and naval vessels for maritime and airborne surveillance. Operational trials are expected soon, positioning India among a small group of nations like the U.S., China, EU, and Japan that are testing photonic radar systems.
(ii) This technology presents multiple applications: detecting stealth aircraft, tracking hypersonic missiles, space debris surveillance, and secure civilian uses in traffic control or disaster monitoring. With trials upcoming, this indigenous radar is set to become a strategic asset in India’s defense toolkit.
