The Deck-Based Multi-Role Helicopter (DBMRH) is set to revolutionize India’s naval aviation capabilities as a specialized naval variant of the Indian Multi-Role Helicopter (IMRH). Designed to meet the diverse operational requirements of the Indian Navy, the DBMRH will incorporate advanced technology, including a planned Airborne Early Warning (AEW) variant equipped with a state-of-the-art radar system. This radar system’s technical specifications promise to enhance situational awareness and operational efficiency.
The DBMRH’s AEW variant, equipped with this advanced radar, will serve as a force multiplier for the Indian Navy. It will enable the detection and tracking of airborne and surface threats, support maritime domain awareness, and provide early warning of potential adversarial activity. These capabilities will significantly enhance fleet protection, maritime surveillance, and network-centric warfare.
The planned AEW radar system for the DBMRH boasts the following advanced features:
- Number of Axes:
- Two axes for enhanced rotational capabilities and precise tracking.
- Mounting Arrangement:
- Optimized for naval applications with robust structural integration to withstand challenging maritime environments.
- Travel Range:
- Designed for comprehensive coverage with azimuth pointing limits of ±35° to -65°.
- Modes of Operation:
- Incorporates multiple operational modes for diverse mission requirements, including search, track, and surveillance.
- Pointing Accuracy:
- Achieves high precision with a pointing accuracy of 1 milliradian (±500 µRad or ±0.03°).
- Scan Rate/Velocity:
- Capable of dynamic scanning rates ranging from 6°/sec to 60°/sec in azimuth, ensuring rapid target acquisition and tracking.
- Azimuth Pointing Limits:
- ±35° to -65° for broad horizontal coverage.
- Elevation Pointing Limits:
- Software-controlled: +5° to -65°.
- Electrical-controlled: +7° to -67°.
- Mechanical limits: +10° to -70°.
- Diameter:
- Compact design with a diameter of approximately 330 ±2 mm, suitable for integration on the helicopter platform.
- Software and Electrical Specifications:
- Advanced software and electrical configurations to support high-performance radar operations in diverse mission profiles.
