Bangalore-based Alpha Design Technologies has secured a contract to supply its new mobile very-high-frequency (VHF) radar to the Indian Air Force (IAF).

Vishal Anand, assistant vice-president of projects at Alpha Design, told Janes at the Aero India 2025 show in Bangalore that the radar can enhance the IAF's capabilities to detect stealth aircraft with low radar cross-section (RCS).

Alpha Design will supply six VHF radars to the IAF with the first expected to be delivered by mid-March, Anand said.

The VHF radar system can be deployed using two 6×6 trucks. One truck carries the radar antenna. The second truck carries the operator station, an uninterruptible power supply (UPS) unit for both vehicles, and an identification friend-or-foe (IFF) antenna, he added.

Anand said the radar is 3D with a range of 360 km. It has 360° coverage and a detection altitude of 15 km. The radar uses solid-state transmit/receive (T/R) modules.

“Signals received by each T/R module is processed by a digital signal processor placed at the back of the radar antenna. Processed signals then get transferred to the control cabin [operator station],” Anand added.

The Indian Army has also expressed an interest in testing this radar, customised according to the service's requirements, he said.
