The Indian Army has unveiled a novel and innovative drone system designed to deceive enemy radar systems, showcasing its commitment to encouraging in-house technological advancements. This system, mounted on quadcopter drones, uses Luneburg lenses to mimic the radar cross-section (RCS) of the Indian Army’s own helicopter fleet, such as gunships and utility helicopters.

The key principle behind this system lies in its ability to create false radar echoes that mimic the signature of actual helicopters. By deploying these “decoy drones” equipped with Luneburg lenses, the Indian Army can mislead enemy radar operators into believing that a larger force of helicopters is present in a specific area. This deception can serve several tactical purposes, including:

Protecting valuable assets:
 By drawing enemy radar attention away from actual helicopters, the decoy drones can shield critical assets from detection and potential attack.

Confusing enemy defenses: The presence of multiple radar signatures can create confusion and uncertainty within enemy ranks, making it difficult for them to assess the true situation and formulate effective countermeasure’s

Enhancing situational awareness: By deploying decoy drones in advance, the Army can gain valuable intelligence about enemy radar capabilities and deployment patterns.

Luneburg lenses are specifically designed to reflect radar waves in a manner that mimics the RCS of a desired object. By attaching these lenses to the quadcopter drones, the Indian Army can effectively create false helicopter signatures on enemy radar screens.

Compared to deploying actual helicopters, this drone-based system offers several advantages. The use of readily available quadcopters and Luneburg lenses makes it significantly more cost-effective. Additionally, the flexibility and maneuverability of drones allow for precise positioning of the “decoy helicopters,” further enhancing the effectiveness of the deception.

The development and deployment of this innovative drone system by the Indian Army represents a significant step towards achieving self-reliance in critical military technologies. This initiative encourages in-house research and development, fostering a culture of innovation within the Indian defense establishment.
