Introduction – Why Sisir Radar Matters in India’s DeepTech Landscape
In recent years, India’s DeepTech ecosystem has witnessed a quiet yet powerful transformation. Among the companies driving this shift, Sisir Radar Private Limited stands out as a compelling case study.
Founded in September 2021, Sisir Radar operates at the intersection of Synthetic Aperture Radar (SAR) technology, Ground Penetrating Radar (GPR), and Hyperspectral Imaging. What makes this company especially notable, however, is not just its technology but how its financial journey, capital structure, and investor backing reflect a startup transitioning from research-heavy beginnings to commercial scalability.
About Sisir Radar Private Limited
Sisir Radar is an Indian spacetech company focused on developing high-resolution Synthetic Aperture Radar (SAR) satellites and advanced radar imaging systems for global Earth observation and surveillance. It offers all-weather, 24/7 monitoring solutions for terrestrial, aerial, and space platforms, enabling imaging even through clouds, fog, darkness, and vegetation. The company aims to develop affordable, indigenous radar technologies with applications in defence, security, disaster management, and strategic monitoring.
Key Application Areas
- Defence – Offers high-resolution, all-weather, real-time intelligence, surveillance.
- Agriculture – Provides all-weather monitoring to detect crop stress, map irrigation, land use and soil moisture.
- Mining – Helps in untapped deposits, curbing illegal operations, managing hazardous terrain and ensuring environmental compliance.
- Urban Planning – building sustainable, resilient and liveable cities.
- Environment – Monitors deforestation, forest health, glaciers and water bodies for pollution, oil spills and sediment levels.
Revenue Trend Analysis
Despite muted revenues in FY2023–FY2024 due to the company being in a technology validation and deployment phase, Sisir Radar delivered a strong inflexion in FY2025, with revenue jumping to ₹217 lakhs, reflecting successful commercialisation.
This sharp acceleration highlights a transition from pilots to scalable contracts, positioning the company for sustained high-growth momentum going forward.
