The Indian Air Force (IAF) has released expressions of interest (EOIs) for the indigenous development of several key components for its Multi-function Phased Array Radar (MPR) system. This system plays a crucial role in air surveillance and target tracking, enhancing the IAF’s air defence capabilities.
The five components for which the IAF seeks indigenous development are:
- IFF Antenna: This antenna transmits and receives Identification Friend or Foe (IFF) signals, allowing the radar to distinguish between friendly and hostile aircraft.
- Rotating Union: This device transfers signals between the stationary radar electronics and the rotating antenna, ensuring uninterrupted operation.
- Central Unit: This unit acts as the brain of the radar system, processing and analyzing radar data to generate track information.
- MAP Motor: This motor drives the rotation of the antenna, enabling the radar to scan a wide area in azimuth.
- GU (Guidance Unit): This unit controls the antenna’s movement and ensures accurate pointing for precise target tracking.
MPR Radar Specifications:
- Type: Indigenous rotating active phased array multifunction 4D radar
- Capabilities: Automatic detection and tracking of aerial targets (fighter aircraft, slow-moving targets)
- Instrumented Range: 400 Km
- Target Detection: 2 sqm RCS targets at 300 Km range
- Altitude Coverage: 100 meters to 30 Km
- Operation Modes: Staring and Rotation
- Rotation Mode:
- Rotation Speed: 7.5 / 15 rpm
- Surveillance Coverage: 360° in azimuth, 30° in elevation
- Staring Mode:
- Fixed Azimuth
- Surveillance Coverage: ±60° in azimuth, 30° in elevation
- Technology:
- Solid state active aperture phased array
- Digital Beam Forming
- Electronic scanning in azimuth and elevation
- Wide transmit beam, multiple receive beams
The successful development of these indigenous components will be a significant achievement for the Indian defence industry. It will demonstrate the country’s capability to design and manufacture complex defence equipment, boosting self-reliance and contributing to India’s strategic autonomy.
