Director, Space Applications Centre
He was born in 1961 in Raigada, Orissa, India. He was awarded the prestigious Sir J C Bose
National Talent Search (JBNSTS) Scholarship in 1981. He has graduated in Electronics and
Telecommunication Engineering from Jadavpur University, Calcutta in 1984
In 1984, he began his career at Space Applications Centre (SAC-ISRO), as digital hardware
engineer and responsible for development of Quick Look Display system of X-band SLAR. Since
then he is involved in development of Microwave Remote Sensing Payloads at SAC.
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. This payload has been launched in 2012.

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
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 is also heading the Office of Innovations Management of ISRO at ISRO Headquarters,
He also 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
He has been Conferred with-
i. “D.Sc.,(Doctor in Science)(Honoris Causa)” by Jadavpur University,Kolkata in 2016
He has been Awarded/Felicitated with-
i. Hari Om Ashram Prerit Vikram Sarabhai Research Award in 2004
ii. ISRO Merit Award in 2008
for his contribution of development of SAR Technology.
iii. ISRO Team Excellence Award in 2012
for RISAT-1 P/L Design and Data Products.
iv. ISRO Team Excellence Award in 2012
for RISAT-1 P/L Fabrication and Qualification
v. "Ruchi Bharat Gaurav Award-2015"
by Ruchi Prativa Foundation, Cuttack.
vi. "7th Acharya P C Ray Memorial Award"

ii. Corresponding Member of International Academy of Astronautics
iii. Fellow of Institution of Electronics & Telecommunication Engineers
iv. Fellow of Indian Society of Remote Sensing
v. Fellow of Indian Society of Systems for Science and Engineering(ISSE)2017.
