DRDO Harnessing Science for Peace & Security Chapter 4: marching forward The article is 41st in the Series of extracts of the monograph, “Defence Research & Development Organisation: 1958-1982”, by Shri RP Shenoy, former Director of Electronics and Radar Development Establishment (LRDE).

ELECTRONICS The major activity in the field of graphical representations were drawn for communications at DLRL in the 1960’s ease of utilisation by the Services. Defence Electronics was the development of On-line Cipher In the first quarter of the 1970’s, Research Laboratory machines which replaced the World the development of the secondary War II Typex machines for clearing surveillance radar was completed. It was Defence Electronics Research large volume of classified traffic on evaluated, accepted and the technology Laboratory (DLRL) which was set up in teleprinter channels. An innovative design was successfully transferred to Bharat 1962, found that the growing application approach based on digital techniques Electronics Ltd, Ghaziabad, which of electronics in defence gave ample for complex key generation, real time produced these in numbers. Collaboration scope for its scientists to gain experience encrypting and decrypting algorithms, between DLRL and BEL ensured that the and build expertise in electronic warfare and synchronisation provided a machine system was contemporary in technology which was in its infancy, on-line ciphers which was competitive on a global and competitive in cost. Based on for teleprinter traffic, HF/VHF/UHF basis. Two versions of on-line cipher the technology of DLRL, indigenous communication antennas and radars. machines were successfully developed and secondary surveillance radars were not Since LRDE’s focus was on speech introduced in the Services. These were only supplied to all the three Services but secrecy, DLRL found a niche in secrecy produced in numbers at the pilot plant were also exported to other countries. systems for teleprinter traffic, which was established by DLRL in 1965. DLRL undertook two more projects being increasingly used by the military. In Unlike radar and communication namely, Indigenization of the SA-75 the first five year period, namely 1962-67, systems, electronic warfare systems are System – code named Project DEVIL, DLRL like LRDE, had to build its human characterised by large bandwidths for and Analog Moving Target Indicator for resource, organise the Laboratory for which octave bandwidth microwave the Radar used in SA-75 system, and the undertaking R&D work, and go through components are crucial.
