Ashwini: Low Level Transportable Radar (LLTR)

The Ministry of Defence (MoD) has taken a significant step toward strengthening India's air defense network by signing a capital acquisition contract with Bharat Electronics Limited (BEL) for the procurement of the ‘Ashwini’ Low Level Transportable Radar (LLTR) for the Indian Air Force (IAF).

About Ashwini Radar

The Ashwini radar is a Low-Level Transportable Radar (LLTR) system designed to provide 4D surveillance, enhancing India’s capability to monitor and respond to aerial threats. It is:

1. An active electronically scanned array (AESA) radar.
2. Built using state-of-the-art solid-state technology.
3. Indigenously developed by the Electronics & Radar Development Establishment (LRDE) of DRDO, in collaboration with Bharat Electronics Limited (BEL).

How Radar works

Key Features

1. Multi-Target Tracking: Capable of detecting and tracking a wide range of aerial targets, including:
   1. High-speed fighter aircraft
   2. Slow-moving objects such as Unmanned Aerial Vehicles (UAVs) and helicopters
2. Instrumented Range: The radar has an instrumented detection range of up to 200 km, making it suitable for long-range surveillance at low altitudes.
3. 4D Surveillance and Electronic Scanning: Integrated with an Identification Friend or Foe (IFF) system.

• Provides electronic scanning in both azimuth and elevation, enabling precise four-dimensional (4D) surveillance — covering range, azimuth, elevation, and velocity.

4. Electronic Counter-Countermeasures (ECCM): Equipped with advanced ECCM capabilities, allowing it to perform efficiently even in environments with electronic warfare threats or jamming attempts.
5. High Mobility and Deployment Flexibility: Designed for rapid deployment, the Ashwini radar is highly mobile, enabling swift relocation and set-up across diverse terrains.
