New Delhi:

The Indian Army has developed an all-weather, all-terrain 'lens'. It can be used to dodge enemy air defence systems during combat. This will help crush and destroy enemy air defense. The name of this lens is 'Lunberg'. The Army has successfully tested the Loneburg lens which attaches to a drone. It will be used to detect enemy weapons, ground forces and aircraft weapons.

How does the Loneburg lens work?
When the Loneburg lens is attached to the drone, the drone's radar capability increases significantly, making it look like a helicopter. Radar cross-section is the target's ability to reflect radar signals onto the receiver. The greater the area of the radar cross-section, the larger the target. Drones have a smaller radar cross-section than helicopters. The Lüneberg lens enhances radar signature and deceives the enemy's air defense system, showing the drone as a helicopter. This will force the enemy to carry out air strikes such as the use of missiles or anti-aircraft guns. The lens has been designed by the Army Design Bureau. If this lens is fitted in a codcopter or a drone, it will emit signals that the enemy will think that it is a helicopter.

This dodging lens has been created by Captain Dheeraj Umesh. "If a swarm of drones (multiple drones) equipped with lenses is sent, it can confuse enemy radars by warning them that attacking helicopters are approaching the target and force them to retaliate," Captain Dheeraj Umesh said.

"The intelligence gathered will be helpful for the future. It can cover 360-degree area on the radar and will reflect radar signals from any direction.
It will help the security forces to ascertain the enemy's weapon position and the type of deployed system, which is helpful in destroying the enemy's Air Defense (SAID).

Drones can be used to hide the planned route of the Army's heliborne operation, where multiple quadcopters can be sent in a direction that dodges enemy radar, making it a suitable alternative to air attack.

In the current era, lenses cannot depict a fighter aircraft but the official said that in future if a UAV or high-speed drone is developed, "we can use the lens to depict the fighter jet".

The all-weather lens
drone was tested in March, where the OSA-AK missile was fired from a distance of 6.5 km and on radar systems in an Electronic Warfare Test (EWT) in October. The drone has a range of 15 km and can fly for 40 minutes. The system can operate in hot deserts and mountainous terrain with high altitudes. The cost of making drones is quite low. A lens costs around Rs 55,000 and the cost per target is around Rs 2.5 lakh, while the current cost is Rs 25-30 lakh per target.
