Major Professional Contributions:

Mr. S Vardarajan has played a key role in indigenous development of several Radar Technologies and Radar Systems. He has established core competency in critical Radar Data processing (RDP) to automatically generate authentic and accurate state estimation on multiple targets in real-time. His pioneering efforts led to development and integration of RDP for family of Indian Doppler Radars (INDRA I & II), Rajendra Multifunction Radar, Ship borne Radars (RAWS-03 and Revathy) and Maritime Patrol Radar. He built RDPs for automatic tracking on hundreds of the surface and aerial targets for indigenously developed land based, ship borne and air borne Radars.

He led the development of a world class, man portable Battle Field Surveillance radar for border security. Over 1400 radars have been produced and supplied to Army. As the Director of LRDE, he was responsible for the successful completion of 3D medium range surveillance radars(Rohini & Revathy), Weapon Locating Radar and Low Level Weight Radars leading to induction to our armed forces..
