Radar Systems

India has developed several advanced radar systems, primarily through the Defence Research and Development Organisation (DRDO). These radars serve various roles, from air defense to artillery tracking and naval applications. Below is an overview of some key radar systems:

Rajendra Radar

Developed by DRDO, the Rajendra Radar is a multifunctional radar system integral to the Akash Surface-to-Air Missile (SAM) system. It is capable of performing surveillance, tracking, and engaging targets with low radar cross-section. Notably, its multi-element antenna setup can be folded flat when the vehicle is in transit.

Indian Doppler Radar (INDRA)

The INDRA series consists of 2D radar systems developed by DRDO for different applications:

• Indra I: A 2D mobile surveillance radar designed for low-level target detection. It is mounted on two wheeled vehicles for mobility.
• Indra II: A variant of the Indra series, this radar is tailored for ground-controlled interception of targets.

Swordfish Radar

The Swordfish Radar is a long-range tracking radar designed by India to counter ballistic missile threats. It is a derivative of the Israeli Green Pine radar, adapted to meet specific Indian defense requirements.

Swathi WLR

The Swathi Weapon Locating Radar (WLR) is a mobile, phased array radar system developed by India. It is designed for counter-battery operations, detecting and tracking incoming artillery and rocket fire, and accurately determining their points of origin for counterattacks.

Aparna

Aparna is a naval radar system that can detect enemy ships and provide early warnings for self-defense. It has already been commissioned into service with the Indian Navy.

Rohini Radar

The Rohini is a 3D radar system developed by DRDO for integration with the Akash SAM system, capable of tracking up to 150 targets simultaneously. The Indian Air Force operates the Rohini, while its naval variant, known as Revathi, is used by the Indian Navy.

AWACS (Airborne Warning and Control System)

AWACS, also referred to as the NETRA Airborne Early Warning and Control System, is an airborne radar platform designed to detect aircraft, ships, and vehicles over long ranges. It plays a critical role in providing early warning and control capabilities.
