Synthetic aperture radar (SAR) is one of the core technologies in the field of remote sensing and measurement. SAR is an active Earth observation system. Because it operates in the microwave band, SAR images are not affected by weather conditions such as clouds, rain, and snow, and can acquire clear surface information in various complex environments. It has important application value in civilian and military fields.
Looking back at the more than 70-year development history of airborne SAR technology, from the introduction of the synthetic aperture radar concept in 1951 to China's first acquisition of SAR images in 1979, and then to the continuous innovation of miniaturization technology, Tianjing Yunhu has taken over the baton of technological inheritance and innovation. Based on the efforts of the founders and the R&D team, we have successfully developed a new lightweight MiniSAR system, pushing the technical indicators to new heights—0.05m ultra-high resolution, ≤2.7kg lightweight design, ≤120W low power consumption operation, and the ability to operate in multiple modes such as strip imaging and spotlight imaging, completely breaking the limitations of traditional SAR systems that are "heavy, large, and expensive".

The MiniSAR system at Tianjing Yunhu is compatible with a full spectrum of flight platforms, including multi-rotor, fixed-wing, and manned aircraft. It has completed integrated flight tests on several mainstream platforms, such as the KWT X6L, HY 1800Pro, DJI M350/M400/FlyCart30, and CW15/CW25E/CW30/CW40/CW100, covering flight tests in different scenarios.

Application Areas:
1. Geological Exploration: SAR technology can detect underground geological structures and rock strata distribution, aiding in the exploration and development of mineral resources.
2. Deformation Monitoring: SAR technology can monitor surface deformation in real time, used for monitoring and early warning of natural disasters such as earthquakes and volcanoes. InSAR technology can measure minute surface deformations, providing crucial data for disaster early warning and risk assessment.
3. Marine Monitoring: SAR technology can detect phenomena such as ocean waves and sea ice, significant for marine meteorology and maritime safety. It can also be used to monitor marine pollution and marine resource distribution.
4. Agricultural Monitoring: SAR technology can monitor crop growth and soil moisture, providing guidance for agricultural production and resource management. Polarimetric SAR technology can distinguish different types of crops and assess their growth and yield.
5. Urban Planning: SAR technology can provide information on urban land use and road traffic, offering data support for urban planning and management. SAR imagery provides a clear understanding of urban spatial layout and traffic conditions, offering a scientific basis for urban planning.
6. Environmental Protection: SAR technology can be used to monitor ecological and environmental information such as forest cover and wetland changes, providing data support for environmental protection and ecological restoration. Simultaneously, SAR technology can also be used to monitor global climate change phenomena such as glacial melting and sea-level rise.
