Making high-end miniature synthetic aperture radar lighter, more affordable, and easier to deploy.

Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. specializes in the R&D and manufacturing of miniature SAR (airborne SAR) products and flight data services. After three years of dedicated development, the company has continuously improved its product innovation, technological iteration, and service upgrades, always prioritizing customer needs. While constantly launching new products, the company has officially expanded into a new business segment—SAR database services—to provide the industry with more professional and comprehensive SAR data solutions.

In synthetic aperture radar (SAR), the L-band has a frequency range of 1 GHz to 2 GHz and a wavelength of 15 to 30 cm, making it the longest wavelength band in radar. Therefore, compared to other bands, the L-band has stronger penetration and better environmental adaptability, giving it unique advantages in deep soil measurement and long-distance inspection. It is the preferred band for agricultural soil moisture monitoring, pipeline leakage detection, forestry surveys, and large-scale surface surveys.

The quality of synthetic aperture radar (SAR) images directly affects the effectiveness of subsequent applications such as target recognition and parameter inversion. But how can we accurately evaluate SAR image quality? Tianjing Yunhu mainly focuses on three aspects: point target analysis, focusing performance (corner reflectors), and signal-to-noise ratio.

For a long time, my country's SAR technology development has faced pain points such as "disconnect between R&D and testing, mismatch between scenarios and needs, and fragmented data and verification." The lack of a professional testing ground integrating full-scenario testing, full-process verification, and full-element adaptation has hindered the rapid iteration and industrial application of technologies such as micro SAR and airborne SAR.

Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. focuses on the research and development and application of miniature synthetic aperture radar (SAR) equipment. Among them, the Lingyun series adopts a frequency-modulated continuous wave operating mode, supports strip, spotlight and hybrid imaging modes, and the system supports all-day and all-weather operation. It can penetrate adverse weather conditions such as clouds, rain and smoke, and perform diverse tasks such as land surveying, pipeline inspection, geological disaster monitoring, agricultural and forestry surveys and border patrols.
