In the field of remote sensing, synthetic aperture radar (SAR) has always been an indispensable core technology. It actively transmits microwave signals, unaffected by clouds, rain, snow, fog, haze, or darkness, enabling it to acquire high-resolution surface information around the clock. However, traditional SAR systems are bulky, heavy, and power-consuming, and have long been limited to manned aircraft or large satellite platforms, making flexible and rapid deployment difficult.
Suzhou Tianjing Yunhu Intelligent Technology Co., Ltd.'s lightweight miniature SAR payload has pushed technical specifications to a new level—0.05-meter ultra-high resolution, a lightweight design of ≤2.7kg, and low power consumption of ≤120W, supporting multiple operating modes such as strip imaging, spotlight imaging, interferometry, and full polarization. This system completely breaks through the limitations of traditional SAR's "heavy, large, and expensive" nature, truly enabling high-precision radar remote sensing to become miniaturized and widespread.
The mounted fixed-wing UAV is a flight platform inherently designed for "wide-area efficiency." Taking the Zongheng CW15 vertical takeoff and landing fixed-wing UAV as an example, its maximum takeoff weight is 16.5kg, and its mission payload limit is 3kg, perfectly matching the Tianjing Yunhu Lingyun lightweight miniature SAR's weight of only about 2kg. Even after being mounted, it maintains a maximum endurance of 180 minutes, a cruising speed of 61km/h, and can complete a wide-area scan of hundreds of square kilometers in a single flight. Compared to multi-rotor drones, fixed-wing platforms have longer endurance (1-8 hours), faster flight speed (60-150km/h), and higher flight altitude, making them more suitable for large-scale, long-distance remote sensing operations.

Our miniature SAR system is compatible with a full spectrum of flight platforms, including multi-rotor, fixed-wing, and manned aircraft, and has completed integrated flight tests on several mainstream models, including DJI M350/M400, and Zongheng CW15/CW25E/CW30/CW40/CW100. Among these, the flight test of the Zongheng CW15 equipped with the Lingyun lightweight model has been successfully completed. All technical indicators met the expected standards throughout the test, and the system output images showed clear outlines, rich details, high target scattering feature recognition, and real-time imaging capabilities enabling immediate data acquisition.
The applications of SAR (Synthetic Aperture Radar) are extremely broad:
1. Disaster Emergency Response: Capable of scanning a 500-square-kilometer disaster area within one hour, identifying inundation zones and landslide hazards, thus gaining crucial time for rescue and relief efforts.
2. Deformation Disaster Monitoring: Utilizing InSAR technology to monitor millimeter-level surface deformation, providing early warnings for building subsidence, bridge deformation, and geological disasters.
3. Maritime Vessel Monitoring: Identifying vessel types and course, monitoring oil spills, and retrieving sea surface wind and wave information, serving shipping safety and marine management.
4. Agriculture and Resource Exploration: Through multi-band penetration and polarization analysis, classifying and identifying crops and monitoring their growth, as well as detecting underground veins and geological structures.
5. Land Surveying and Pipeline Inspection: Large-scale, high-precision topographic mapping and infrastructure inspection, improving efficiency by over 60% and reducing costs by over 50%.
The deep integration of miniature synthetic aperture radar (SAR) with fixed-wing UAVs is reshaping the technological boundaries of remote sensing monitoring with its core advantages of all-weather operation, high precision, long endurance, and wide coverage, providing efficient, flexible, and low-cost new remote sensing solutions for various industries.
