Browse: 60 Time: 2025-02-25

合成孔径雷达(SAR)是一种获得高分辨率地表图像的雷达技术。其基于飞控器或地面站点的雷达发射脉冲,接收反射回来的信号,计算出每一个像素的相位和幅度,进而构成高分辨率的图像,一般适用于遥感、军事、地质勘探及地貌研究等领域。


而随着无人机技术的快速发展和合成孔径雷达(SAR)的小型化趋势,将轻量化SAR系统集成到行业级无人机平台已成为遥感领域的重要研究方向。围绕大疆M350这一款高性能行业无人机,我司特别推出与之完美适配的减重版MiniSAR系统。本文将从技术适配性、图像成像效果以及适配应用领域三个方面分析这一组合的可行性。


平台性能匹配:大疆 M350 RTK最大负载能力达 2.7kg,续航时间 55分钟(空载)/32分钟(满载),具备IP55防护等级和6级抗风能力。目前我司最轻的MiniSAR系统(凌云系列LY1B)重量已控制在2.7kg范围内,功耗低于200W。具备单极化、全极化、条带、聚束等模式,能够实现实时成像。二者的物理参数匹配度较高,满足基本搭载需求。

系统应用领域: 无人机MiniSAR技术可以在复杂地形和隐蔽环境下进行目标探测。无人机配备SAR设备可以深入到森林、山区等人类无法到达的复杂地域,对地面目标进行探测和观测。或者在执行搜救任务时,帮助人们快速定位被困者的位置,提高搜救的效率和准确性。以下是一些常见的应用领域:


1.应急灾害监测

洪涝区域淹没范围实时测绘

山体滑坡形变监测

夜间搜救目标识别


2.基础设施巡检

输电线覆冰厚度反演

海上舰船安全状态定位

桥梁大坝结构形变监测


SAR技术在无人机领域的应用具有天气不受限制、复杂地形下探测能力强、高分辨率图像等优势。而大疆M350与我司的减重版MiniSAR集成度较高,操作简便,响应迅速。这一技术组合有望在应急管理、能源管理、农业管理、军事管理等领域发挥强大的作用!

Tianjing Yunhu | MiniSAR: Full Polarimetric Imaging Capability

In the field of remote sensing today, synthetic aperture radar (SAR), visible light, and infrared together form a multi-layered observation system. Visible light remote sensing is intuitive and clear, while infrared remote sensing excels at thermal sensing. However, both are passive detection methods, heavily reliant on sunlight or the target's own thermal radiation. Once they encounter cloud cover, nightfall, or rainy/foggy weather, their detection capabilities are significantly reduced or even completely lost.

Tianjing Yunhu | P-band Airborne SAR Radar System

Low-frequency radars (such as P-band and L-band radars) can "see farther and see more clearly" because of their longer wavelengths, lower attenuation, and reduced sensitivity to stealth coatings. In modern air defense systems, they are key to anti-stealth radars. They can penetrate 1-meter-thick camouflage netting and 3-meter-thick bushes to identify hidden tanks and radar stations, and are less likely to trigger enemy warning systems, demonstrating significant advantages in covert detection.

Tianjing Yunhu | Miniature SAR Vehicle Target Dataset

Synthetic Aperture Radar (SAR) target detection datasets are a core foundation for training and evaluating deep learning models. These datasets cover various target types, including ships, aircraft, vehicles, bridges, and oil tanks, and are applicable to multiple fields such as military reconnaissance, maritime monitoring, and traffic management. They not only provide high-resolution SAR images but also contain precise annotation information (category, location, size, etc.), ensuring improved algorithm performance.

Tianjing Yunhu | Miniature SAR Equipped with Fixed-Wing UAV

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.

Tianjing Yunhu | Airborne SAR (Synthetic Aperture Radar) Calibration Capability

Airborne SAR (Synthetic Aperture Radar) calibration refers to the calibration of various parameters of an airborne SAR system using specific methods to eliminate systematic and environmental errors, thereby ensuring the quality of SAR images, positioning accuracy, and the accuracy of inversion parameters. Airborne SAR calibration is mainly divided into three categories: geometric calibration, radiometric calibration, and polarimetric calibration.

UAV L-band Heavy Orbit Interferometric SAR System: Airborne Verification for Millimeter-Level Deformation Monitoring

Synthetic Aperture Radar Interferometry (InSAR) technology, with its all-weather, 24/7 capability and high sensitivity to surface deformation, has become an important tool for geological hazard monitoring, ground subsidence investigation, and infrastructure health diagnosis. Integrating InSAR technology onto unmanned aerial vehicle (UAV) platforms further overcomes the limitations of long satellite revisit cycles, insufficient maneuverability, and high costs associated with manned operations, providing a new approach for regional, high-frequency, and high-precision deformation monitoring. However, the small size and susceptibility of UAV platforms to airflow disturbances make it difficult to maintain consistent flight paths during repeated flights, posing a significant challenge to double-track interferometry processing.
