About Lab

Defence Electronics Research Laboratory (DLRL) was established in 1961 under the aegis of Defence Research and Development Organization (DRDO), Ministry of Defence, to meet the needs and requirements of electronic systems of Indian Armed Forces. DLRL has been entrusted with the primary responsibility of the design and development of Electronic Warfare systems covering radar and communication frequency bands for the Indian Army, Air-force and Navy. In close coordination with various production agencies, other DRDO/National Laboratories and academic institutions, DLRL has designed, developed and produced a large number of ruggedised Electronic Warfare (EW) Systems meeting the state-of-the-art requirements of Army, Navy and Air-force in a dynamically changing operational scenario. Electronic warfare systems developed by DLRL have been inducted into the Services after rigorous field evaluation and user exploitation.

The testing and evaluation of EW systems demand huge infrastructure, test and evaluation facilities. To cater to this requirement ELSEC was established in the year 1998 as an extension of the Defence Electronics Research Laboratory, Hyderabad. It consists of state-of-the-art infrastructure to meet the critical integration and evaluation requirements of ongoing and future programmes. Laid out in 180 acres of land, it is being extensively used for integration , and testing of complex Electronic Warfare Systems. Modern EW system simulation and modeling facilities are located inside ELSEC to carry out simulation of complex systems.
