BEL-DRDO Anti-Stealth VHF Radar Set to Debut at Aero India 2025

In a significant advancement for India's defense capabilities, Bharat Electronics Limited (BEL), in collaboration with the Defence Research and Development Organisation (DRDO), has developed an advanced Very High Frequency (VHF) radar designed to detect stealth aircraft. This state-of-the-art radar system was officially launched on January 29, 2025, at BEL's facility in Ghaziabad.

Understanding VHF Radar Technology

VHF radars operate within the frequency range of 30 to 300 MHz. Unlike conventional radars that operate at higher frequencies, VHF radars utilize longer wavelengths, which interact differently with aircraft surfaces. Stealth aircraft are engineered to evade detection by higher frequency radars through design features and materials that minimize their radar cross-section (RCS). However, these stealth features are less effective against the longer wavelengths of VHF radars, making such aircraft more detectable.

Key Features of the New VHF Radar

• Staring Capability: The radar is equipped with a "staring capability," allowing it to continuously monitor a specific area. This enhances its ability to detect and track stealth targets at extended ranges.

• Extended Detection Range: The system can track aerial targets beyond 100 nautical miles, providing early warnings of potential threats.

• Mobility: Mounted on two TATRA vehicles, the radar is designed for rapid deployment and can be easily relocated to adapt to changing security needs.

Strategic Advantages

The integration of this VHF radar into India's air defense network exemplifies a layered defense approach, combining different radar technologies to achieve comprehensive coverage and effectively counter stealth threats. Stealth aircraft are less likely to be equipped with countermeasures effective against VHF frequencies, enhancing the radar's effectiveness.

Upcoming Showcase at Aero India 2025

The radar will be featured at Aero India 2025, offering defense experts and industry leaders a first-hand look at its capabilities. This event will provide an opportunity to demonstrate the system's advanced features and its role in strengthening India's air defense infrastructure.

The development of this advanced VHF radar marks a pivotal step in India's indigenous defense technology, significantly enhancing the nation's ability to detect and respond to modern aerial threats.
