天镜韵湖 | 凌云系列Ku波段SAR雷达搭载科卫泰无人机飞行测试

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.

机载SAR（合成孔径雷达）定标是指通过特定的方法对机载SAR系统的各项参数进行校准，以消除系统误差、环境误差，从而保证SAR图像的质量、定位精度和反演参数的准确性。机载SAR定标主要分为几何定标、辐射定标和极化定标三大类：

合成孔径雷达干涉测量（InSAR）技术凭借其全天时、全天候的工作能力以及对地表形变的高灵敏度，已成为地质灾害监测、地面沉降调查与基础设施健康诊断的重要手段。将InSAR技术搭载于无人机平台，进一步突破了卫星重访周期长、机动性不足以及有人机作业成本高的局限，为区域性、高频率、高精度的形变监测提供了全新路径。然而，无人机平台轻小、易受气流扰动，其重复飞行航迹难以保持一致，这给重轨干涉处理带来了严峻挑战。

合成孔径雷达（SAR）作为一种主动微波遥感系统，能够主动发射微波并接收目标反射的回波，不受光照和天气条件的限制，实现全天时、全天候的快速成像。当SAR技术与无人机平台深度结合，更突破了传统卫星和有人机SAR在时效性、灵活性和成本方面的诸多限制。

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.
