Photonic radars use two laser beams to generate high-frequency RF signals, offering advantages like higher detection capability and jam-resistance.
They can provide sharper target detection with purer signals and high bandwidth, making them lighter and more efficient due to the absence of copper components.
DRDO has a working prototype of photonic radars with GaN semiconductors, although challenges like access to specific materials may hinder mass production in India.
India's development of photonic radars marks progress in catching up with other countries exploring advanced radar technologies like quantum radar and terahertz radar.
