Synthetic Aperture Radar (SAR) is an advanced radar technology capable of penetrating darkness and fog to acquire high-resolution images of the Earth's surface. It transmits pulse signals via airborne or ground-based platforms and analyzes the reflected phase and amplitude information to construct detailed ground images. SAR is widely used in remote sensing mapping, geological exploration, disaster monitoring, and national defense.

Today's main focus is on the CW-25E VTOL fixed-wing UAV and the Tianjing Yunhu XiangYun System pulse MiniSAR.

The CW-25E is a pure electric VTOL fixed-wing UAV designed specifically for large-area missions. It has a fuselage length of 2.08 meters, a wingspan of 4.35 meters, and features a twin-boom fused inverted V-tail design, resulting in a compact structure and excellent aerodynamic performance.

The CW-25E has a maximum takeoff weight of 31.58 kg and a payload capacity of 6.6 kg, capable of simultaneously carrying various mission equipment such as SAR, lidar, and electro-optical pods. It boasts a maximum endurance of 150 to 240 minutes, a service ceiling of 6000 meters, a maximum takeoff altitude of 4000 meters, and wind resistance up to level 7. It can stably perform patrol missions in complex terrain and high-altitude areas.

Airborne synthetic aperture radar (SAR) has gradually become the "main force" in the field of low-altitude remote sensing due to its technical advantages of all-weather, all-time, and high resolution. It has performed particularly well in terms of real-time data, high-precision imaging, and dynamic and static target monitoring, providing new technical solutions for various application scenarios, especially in the fields of maritime surveillance, topographic mapping, power line inspection, and urban planning.

Airborne synthetic aperture radar (SAR) refers to radar mounted on an aircraft or drone that transmits microwave signals to the ground while in flight, then receives the reflected echoes and, after a series of calculations and processing, generates a clear "microwave photograph." Unlike ordinary optical cameras, SAR's biggest advantage is its all-weather, all-day capability; it can take pictures day and night, and is unaffected by wind or rain.

The “SAR Integrated Display and Control Software” is the core human-machine interface of the Synthetic Aperture Radar (SAR) system. It is responsible for processing, displaying and managing the data generated by the radar system, and enabling operators to control and monitor the operation of the entire system in real time and effectively.

In scenarios such as geological disaster early warning, health monitoring of large bridges, and settlement observation in mining areas, surface displacements that are imperceptible to the naked eye often harbor enormous risks. How to efficiently, accurately, and cost-effectively capture these "millimeter-level" changes is an important research direction in the field of modern remote sensing.
