While former ISRO scientist S Nambi Narayanan has been “falsely” projecting himself as father of Vikas engine and the lone victim of the fake espionage case, espcially through the movie – Rocketry: The Nambi Effect – in sharp contrast, we have another distinguished scientist Tapan Misra, whose contribution to India’s Space Programme is immense.

Tapan Misra was superceded and denied the top ISRO post obviously due to reckless maneuvering by some vested interests and was also allegedly poisoned by certain unidentified elements. After his retirement from ISRO, Tapan Misra has been working silently for the cause of the nation by working on his startup – SISIR Radar.

Acknowledged as a global expert in Imaging Radar, Tapan Misra was the Director of two of ISRO’s most prestigious centres, Space Applications Centre (SAC) and Physical Research Laboratory (PRL).

Tapan Misra also is the principal architect of RISAT series of radar imaging satellites, which are the backbone of India’s many tactical, strategic and civilian applications. He is also the lead designer of NASA ISRO dual frequency SAR (NISAR) which is scheduled to launch by 2023.

SISIR Radar is building indigenous, low cost, high resolution, innovative SAR systems for commercial and strategic use.

Co-Founder of SISIR Radar Urmi Bhambhani has led the development of NLP-based AI education products for an edtech startup, built complex large-scale distributed operating systems at NetApp. She is a university rank holder from VIT and a brilliant computer engineer who is passionate about technology.

Soumya Misra, also Co-Founder of SISIR Radar has vast global manufacturing experience, from GPU designing at Intel to smartphone design and manufacturing at Creo, a Sequoia-funded startup which was acquired by Hike. The IIT Kanpur graduate.

Soumya Misra, along with Urmi Bhambhani, started Summachar, an infographic news platform for Gen Z.

The USP of SISIR Radar is:

• Best-in-class Synthetic Aperture Radar (SAR) image processor
• All-weather, day and night, stable data source
• Daily high resolution SAR imagery across the world
• High temporal frequency data collection
• Distributed, asynchronous imaging coverage at fractional costs

Synthetic Aperture Radar (SAR) is a special type of flying radar which captures high resolution microwave imagery by leveraging the motion of the radar. Whereas traditional mapping cameras are slower, capture smaller area within the same time and are completely dependent on daylight and favourable weather conditions to work.

SAR is a very sophisticated technology that involves highly complex maths. Making it drone-borne, further complicates the system due to motion compensation. This makes SAR a technology much unexplored. Currently, inferior daylight-dependent camera-based drones are available in the market.

An expert team of Scientists is working at at SISIR Radar, led by Chief Scientist Tapan Misra. He is one of the world’s foremost experts in Synthetic Aperture Radar (SAR) Technology and the principal architect of RISAT – India’s first cutting-edge SAR-based reconnaissance satellite.

SAR is available commercially but only on satellites or aeroplanes, making it extremely costly and irregular.

According to Tapan Misra, with their drone-borne SAR you get space-grade images on-demand in a very cost-effective manner!

Application

Defence and National Security: Border areas are very sensitive regions and see a lot of infiltration at night time. Drones present in the market have a short monitoring range and are practically useless in the absence of light. SISIR Radar’s path-breaking drone-borne Synthetic Aperture Radar (SAR) can capture footage in any weather, even in pitch darkness and from far distances which not only safeguards the life of soldiers and drone operators but are also cost effective as Sisir Radar offers the world’s most affordable SAR.

Mining: From monitoring the site for security to stockpile tracking in opencast mines, Sisir Radar drone-borne Synthetic Aperture Radar (SAR) can do the job for you even at night.

Crop Insurance: A majority of farmers can’t have their crops insured because of the present difficulty in surveying the farmlands on foot. Now what takes hours, can be diminished into a matter of a few minutes thanks to our drone-borne Synthetic Aperture Radar (SAR). This enables banks to carry out accurate surveys to judiciously give out loans.

Land Survey: With the help of the world’s only drone-borne Synthetic Aperture Radar (SAR), you can easily monitor vast stretches of land within minutes at high resolution. Further, SISIR Radar data processing algorithms which integrate AI & ML help provide actionable insights from that data. From far one can determine physical characteristics of an object like the material it is made of. SAR signatures can be used for tree identification as well.

Urban Planning: With a rapid increase in urbanisation, more and more townships are coming into existence. A major concern in such newer areas is land subsidence. It is a phenomenon where the land caves in, generally due to the withdrawal of groundwater below it. Our unique SAR technology has the ability to detect possible land subsidence occurrences and warn urban planners beforehand.

Agriculture Planning: From yield prediction to crop assessment, with the help of SISIR Radar drone-borne Synthetic Aperture Radar (SAR), one can get the data at any time you want. SAR enables to accurately measure plant health so that you can take necessary steps on time to ensure better crop production.
