Man portable BFSR-SR in use with Indian Army.
The PJT-531 Battle Field Surveillance Radar (BFSR-SR) is a man portable system developed by DRDO to detect, track and classify moving surface target like crawling and walking men, light and heavy vehicles and low flying helicopters.
The system can operate in all weather during day or night.
It can be transported by three infantry soldiers and installed in 5-mins, is easy to operate and can track multiple threats while continuing to scan.
The radar can be operated from up-to 100 meters away using a field cable by soldiers from the safety of their bunkers or trenches.
BFSR-SR with co-mounted IR sensor for enhanced target information is also available.
The radar was developed by Bangalore-based laboratory Electronics and Radar Development Establishment (LRDE) and is being produced by M/s BEL.
Over 1,400 BFSRs have been purchased by the Indian Army to check infiltration along the LOC.
