We operate a professional flight team holding all legal qualifications required for commercial flight operations;
We provide a full-chain solution covering “radar R&D + platform integration + flight operations + data processing + industry applications.”
Product Features:
The airborne miniature synthetic aperture radar (MiniSAR) series from Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd. offers all-weather, all-time, long-range, high-resolution, and multi-mode capabilities. The system adopts Frequency Modulated Continuous Wave (FMCW) or pulse modulation, featuring low cost, lightweight design, and high efficiency. It supports multiple technical modes including real-time imaging, Ground Moving Target Indication (GMTI), active phased array, and Differential Interferometric SAR (DInSAR), with resolution reaching centimeter level. The series can be mounted on a variety of flight platforms such as multirotor UAVs, vertical take-off and landing (VTOL) fixed-wing UAVs, helicopters, and manned aircraft, and shows broad application prospects in both civilian and military domains.
Product Portfolio Overview:
Lingyun Series:
This is a standard-configured radar based on Frequency Modulated Continuous Wave (FMCW) technology. It supports both single-polarization and full-polarization modes, as well as stripmap scanning and real-time imaging. Weighing only 4.5 kg, it is perfectly adaptable to a wide range of flight platforms and provides all-weather, all-time remote sensing acquisition capability. The lightweight version weighs just 2.7 kg or even less, with notable advantages of low cost, compact size, low power consumption, and light weight, making it suitable for deployment on various fixed-wing, multirotor, and small UAV platforms.

Yunyuan Series:
This system is designed to meet deformation-monitoring needs across a variety of industries. Operating in the L-band, the system integrates a high-precision fiber-optic inertial navigation system, a high-performance servo-stabilized platform, and Differential Interferometric SAR (DInSAR) processing technology. It is compatible with professional software workflows such as GAMMA. It can precisely detect millimeter-level micro-deformations of ground surfaces, buildings, bridges, and other targets, and generate high-precision deformation maps, providing strong technical support for geological disaster early warning, infrastructure monitoring, and related fields.

Yunying Series:
This system comprises an X-band InSAR and a P-band fully polarimetric SAR, adopting left-looking and right-looking antenna pod configurations. Bilateral-looking polarimetric imaging is achieved through electronic switching. The P-band can penetrate vegetation to acquire bare-earth Digital Elevation Models (DEM), while the X-band delivers high-resolution Digital Surface Models (DSM) of the target area. The two bands complement each other, providing all-time, all-weather high-resolution radar image data, digital surface models, and polarimetric interferometric SAR image data. Using these datasets, the position information of targets can be accurately inverted.

Co-View System:
This system ingeniously integrates SAR, visible-light, infrared, and multiple other imaging technologies, enabling multiple sensors to simultaneously image the same scene and delivering a “one flight, multiple images” capability. The improved imaging efficiency allows flexible deployment across a variety of scenarios. By leveraging the unique imaging mechanisms of different technologies and combining the registered images, we obtain more comprehensive image information and more accurate analytical results.
