DRDO Unveils India’s First Indigenous Photonic Radar for Advanced Stealth Detection.

Science and Technology | Dated: 01 Jul 2025

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.

🎯 Key Highlights:

- 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.

💡 Other Important Facts:

(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.
