Sisir Radar Unveils World’s First and Highest-Resolution L+P Band SAR, Revolutionizing Remote Sensing

Sisir Radar, a pioneering space sector start-up, has achieved a groundbreaking milestone in Synthetic Aperture Radar (SAR) technology by developing the world’s first and highest-resolution L+P band SAR system. This innovation marks a major leap forward in remote sensing, with critical applications in strategic reconnaissance, disaster management, and environmental monitoring.

The company has successfully tested its L-band SAR on a drone, achieving an unprecedented resolution of 0.2 meters—setting a new global standard in L-band SAR technology. Additionally, Sisir Radar is working on integrating both L and P bands to operate simultaneously from a satellite-borne SAR system. This breakthrough enhances penetration capabilities through clouds, heavy rainfall, dense vegetation, and even underground layers in dry terrains, making it an invaluable asset for defense, intelligence, and scientific research.

Sisir Radar’s rapid progress has been fueled by its success in the iDEX DefSpace Challenge, which has propelled the development of L/P band Continuous Wave SAR payloads for Low Earth Orbit (LEO) small satellites. The company is also developing an unfurlable, electronically steering antenna tailored for the Indian Air Force (IAF), further solidifying its position as a leader in cutting-edge radar technology.

The team behind Sisir Radar is led by Dr. Tapan Misra, a former ISRO scientist and a renowned expert in radar and space technology, alongside Soumya Misra, the Co-Founder and CEO. Their combined expertise has driven the company’s ambitious roadmap, which aims to revolutionize space-based surveillance and remote sensing solutions.

The integration of L and P bands offers significant advantages over conventional SAR frequencies like X-band, especially in tropical regions where penetrating dense foliage and challenging terrains is crucial. The P-band, in particular, enhances underground and subsurface imaging, providing superior capabilities for geological surveys, archaeological studies, and defense applications.

With its cutting-edge SAR technology, Sisir Radar is poised to disrupt the global SAR data market by delivering unparalleled resolution, coverage, and affordability. Its innovative approach is set to redefine how governments, defense agencies, and industries utilize remote sensing, ensuring a new era of advanced, high-precision radar solutions.
