India’s Defence Avionics Research Establishment (DARE) a premier lab of DRDO based in Bangalore has developed an indoor antenna test range facility to characterize both the electronic support measure (ESM) an electronic counter measure (ECM) antennas which is first of its kind in India.

This unique facility covers a wide range of for pattern characterisation with a unique capability to measure direction finding accuracy also. It is also capable of characterizing antennas for radiation patterns, beam peak, beam with width and directivity. The chamber is completely tested by DARE experts and is now fully operational.

Keeping in mind of the signals that would be received and transmitted by electronic warning antennas, similar to sun rays, the facility is named as UDAYAKIRAN.

Latest achievement of DARE has been upgrading the entire MiG-27 fleet of Indian Air force.
