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.
Addressing the existing pain points in the industry and the urgent needs of industrial development, Tianjing Yunhu has been deeply involved in the SAR technology field. Leveraging its years of accumulated core algorithms, self-developed product system, and industry resource advantages, it has precisely planned and built the nation's first dedicated SAR testing base, providing a massive platform for systematic, large-scale, and scenario-based SAR testing in China.
I. Breaking the Mold: China's First Airborne SAR Test Platform
Located in the core area of Zhouzhuang, Kunshan, the base covers an area of over 40 square kilometers and is equipped with a dedicated, 400-meter-high independent airspace year-round. This completely breaks through the industry's common problems such as cumbersome airspace approval, limited flight testing, and insufficient test frequency, ensuring the efficient and routine conduct of various SAR flight tests.

Flight test site
Meanwhile, the surrounding natural and cultural landscape is rich and diverse, encompassing road networks, lawns and open spaces, lakes and waterways, farmland and woodlands, residential complexes, and hilly terrain, highly replicating various real-world scenarios such as national defense reconnaissance, geological deformation monitoring, natural resource mapping, river and lake embankment inspection, and remote sensing. It can comprehensively adapt to the real-world testing needs of multiple types of SAR products, establishing a closed-loop system of "R&D and prototyping—real-world flight testing—performance verification—scenario validation," providing a one-stop, full-chain testing and verification service for various SAR systems, from laboratory prototypes to real-world deployment.
Beyond a top-notch flight test site, the company is simultaneously improving its industrial support and customer service systems. Suzhou Yunjing Intelligent Technology Co., Ltd. (hereinafter referred to as "Yunjing"), a subsidiary of Tianjing Yunhu, focuses on data services and has equipped itself with a dedicated customer delivery center of over 1,300 square meters within the Zhouzhuang Binhu Low-Carbon Production Park, serving as a core supporting facility for the base. The delivery center boasts a comprehensive layout, featuring standardized training classrooms, multi-functional business meeting rooms, dedicated rest areas, and a data processing room. It can fully support diverse needs such as client technical collaboration, product delivery and acceptance, industry-academia-research training, industry technical exchanges, and specialized skills training. It streamlines the entire process from "real-world testing + theoretical teaching + implementation," providing partners with professional, comprehensive, and integrated technical services and industry-academia-research training solutions, helping upstream and downstream enterprises and research institutions efficiently implement technologies and cultivate talent.




II. Robust Support, Building a Full-Chain Testing System
As the core carrier for the technological innovation and application of Tianjing Yunhu, the testing base focuses on the needs of the entire SAR technology lifecycle, constructing a four-in-one full-chain testing system integrating "hardware testing + flight testing + data verification + application simulation." Its core capabilities lead the industry:
Full-Type Radar Adaptation Testing: The base is fully compatible with Tianjing Yunhu's two core product lines: the Lingyun series frequency-modulated continuous wave SAR and the Xiangyun series pulse-type SAR, covering multiple bands including P, L, C, X, Ku, Ka, and W. It supports various operating modes such as single polarization/full polarization, strip/spotlight, and interferometry, and can complete multi-dimensional tests on radar performance, environmental adaptability, and stability.


Full-platform flight test verification: It is compatible with a full range of flight platforms, including multi-rotor UAVs, vertical take-off and landing fixed-wing UAVs, and manned aircraft. It has completed integrated flight tests on multiple mainstream platforms such as DJI M350 and CW-100. It can carry out flight tests in different scenarios such as low-altitude close-range fine imaging and mid-to-high-altitude wide-area coverage to verify the SAR system's all-weather and all-time operation capabilities under complex weather and terrain conditions.



High-Precision Data Processing and Verification: Equipped with a professional SAR data processing center, featuring independently developed high-precision imaging algorithms and deformation analysis software, it can process raw data acquired from flight tests in real time, generating high-resolution SAR images, millimeter-level deformation monitoring reports, and other products, providing precise data support for technology optimization and application implementation.
Multi-Scenario Application Simulation and Demonstration: Leveraging the base's diverse terrain environment, simulated application scenarios such as defense camouflage assessment are built to conduct realistic combat simulation tests, verifying the application effectiveness of the SAR system in different industry scenarios and accelerating the transformation of technological achievements into industry solutions.
III. Looking to the Future: Building a Global SAR Innovation Hub
From independently developing miniature SAR products to building the first SAR test base in China, Tianjing Yunhu has always aimed to "become a globally leading synthetic aperture radar solution provider," adhering to its original aspiration of serving the country through science and technology, and deeply cultivating innovation in the SAR field.
In the future, Tianjing Yunhu will continue to increase investment in the construction of the test base, continuously improve the testing environment, upgrade the testing equipment, and optimize the service system, striving to build the base into a leading domestic and world-class SAR technology innovation center, testing and verification center, and application demonstration center.
