Director, Space Applications Centre
He was born in 1961 in Raigada, Orissa, India. He has graduated in Electronics and
Telecommunication Engineering from Jadavpur University, Calcutta in 1984. He was awarded
the prestigious Sir J C Bose National Talent Search (JBNSTS) Scholarship in 1981.
Since 1984, he is involved in development of Microwave Remote Sensing payloads in Space
Applications Centre (SAC-ISRO), Ahmedabad. He began his career as digital hardware engineer
responsible for development of Quick Look Display system of X-band SLAR.
He was lead member of the team which designed and developed C-band Airborne SAR (ASAR),
implementing full motion compensation. He developed FFT based Real Time Sub-aperture (FFTRTS) algorithm for real time processing of SAR during his tenure as Guest Scientist in German
Aerospace Agency (DLR) in 1990.
During 1995-1999, as Project Manager for system engineering of Multi-frequency Scanning
Microwave Radiometer (MSMR) payload for IRS-P4, he contributed mainly in the field of system
design, simulation, integration, checkout and ground calibration for MSMR payload. He was also
responsible for development of cryogenic blackbody targets for ground characterisation of MSMR
payload. He led the team which developed a multi-resolution, multi-swath airborne SAR system
called DMSAR (SAR for Disaster Management) in 2005-2006. He also invented the algorithm called
track steering algorithm for high resolution processing of DMSAR. He also led the development
of Scatterometer payload for Oceansat-2 which was launched in 2009 and providing valuable wind
vector data to global meteorological community.
He was the lead designer for development of C-band SAR Payload based on active antenna
concept. His leadership has resulted in partnership with Indian Industry in developing critical
technology elements needed for RISAT like MMICs, TR modules, miniaturised pulsed power
supplies and ASIC based TR controllers. This partnership has important element of qualification
of processes and personnel for production of Space Grade Electronics apart from industrial
development and production. Presently this payload has been launched in 2012.
He is also heading the Office of Innovations Management of ISRO at ISRO Headquarters,
As Deputy Director, of Microwave Remote Sensors Area, he led the team to develop futuristic
remote sensing systems like DBF based S-band SAR for NI-SAR, L-band SAR, very agile high
resolution X-band SAR, mm-Wave sounders and advanced Scatterometer.
He was awarded Hari Om Ashram Prerit Vikram Sarabhai Research Award in 2004 and ISRO
Merit Award in 2008 for his contribution of development of SAR Technology. He was felicitated
with "Ruchi Bharat Gaurav Award-2015" by Ruchi Prativa Foundation, Cuttack. He was
conferred with "7th Acharya P C Ray Memorial Award" in 2016, by Institute of Pulmocare and
Research Institute, Kolkata. He was conferred with “Degree of Doctor in Science (Honoris Causa)”
by Jadavpur University, Kolkata.
He was elected as -
a. Fellow of Indian National Academy of Engineering in 2007.
b. Corresponding Member of International Academy of Astronautics in 2008.
c. Fellow of Institution of Electronics & Telecommunication Engineers in 2016.
d. Fellow of Indian Society of Remote Sensing in 2016.
He has 2 granted patents, 6 pending patents, 5 copyrights and more than 25 papers to his credit.
