Sisir Radar
Sisir Radar is a Kolkata-based deep-tech spacetech startup, founded in 2022 by Dr. Tapan Misra (former Director of ISRO's Space Applications Centre and architect of India's RISAT SAR program), developing SAR systems for drone, airborne, and spaceborne platforms across P/L/S/C/X frequency bands. It is targeting India's first privately developed L-band SAR satellite and has won two iDEX challenges to build specialised SAR satellites for the Indian Air Force.
