BFSR-SR or Battlefield Surveillance Radar is state-of-the-art lightweight, man- portable battery-powered electronic short range battlefield surveillance radar developed by the Defence Research and Development Organization (DRDO) to provide all- weather surveillance against intrusion.

The BFSR has been designed by DRDO's Bangalore-based laboratory, the Electronics and Radar Development Establishment (LRDE) and is being manufactured by Bharat Electronics Limited (BEL).

The radar is capable of searching a specified sector and performing track while scanning for multiple targets. The radar detects, tracks, and aids in classifying the moving targets.

The entire radar system is carried by two soldiers and operated on a tripod. The radar is compact and weighs about 27 kg (packed in two modules; each weighing not more than 15 kg) and can be set up within six minute to match the speed and requirements of the users.
