全球SAR卫星市场(2023-2033)Global SAR Satellite Market 2023-2033 |
配备合成孔径雷达 (SAR) 感测器的遥感卫星利用雷达技术捕捉地球表面的高解析度影像。 SAR 卫星使用的微波频率可以穿透云层、黑暗,甚至某些类型的植被,这与依赖可见光或红外光的光学感测器不同。
这就是合成孔径雷达的工作原理:人造卫星向地球表面发送微波讯号。 SAR 感测器收集反射讯号并测量讯号返回所需的时间。 SAR 卫星可以透过分析返回讯号的相位和幅度来产生地球表面的详细影像。
SAR卫星可以产生精度达到几公尺的高解析度影像。 解析度由微波讯号的频率、天线的尺寸、卫星与目标之间的距离等因素决定。 土地覆盖、地形、地表变形和随时间的变化都可以透过 SAR 影像来揭示。
SAR 卫星的主要优点之一是它们可以在任何天气和照明条件下运作。 与光学感测器受到云、雾霾和黑暗的限制相比,SAR可以穿透这些障碍,适合在阴天和夜间拍摄。
SAR 影像用于绘製土地覆盖图、监测植被并检测生态系统的变化。 它有助于监测森林砍伐、海岸侵蚀和地面沉降。 SAR 还可以帮助检测石油洩漏并评估洪水和地震等自然灾害。 SAR 卫星也用于军事应用,例如监视、侦察和战略地形测绘。 SAR 卫星可以探测和追踪移动物体、监视边境地区并提供偏远地区和敌对环境的态势感知。 桥樑、水坝、管道、道路等是SAR卫星监测的一些基础设施。 它可以检测地面变形和沈降,识别潜在危险,并协助评估结构的健康状况。

Remote sensing satellites equipped with Synthetic Aperture Radar (SAR) sensors capture high-resolution images of the Earth's surface using radar technology. SAR satellites use microwave frequencies to penetrate clouds, darkness, and even some types of vegetation, as opposed to optical sensors that rely on visible or infrared light.
The satellite sends microwave signals to the Earth's surface, which is how Synthetic Aperture Radar works. The SAR sensor collects the signals that bounce back and measures the time it takes for the signals to return. SAR satellites can generate detailed images of the Earth's surface by analyzing the phase and amplitude of the returned signals.
SAR satellites are capable of producing high-resolution images with details as small as a few meters in size. The resolution is determined by factors such as microwave signal frequency, antenna size, and distance between the satellite and the target. Land cover, topography, surface deformation, and changes over time can all be revealed by SAR images.
One of the key advantages of SAR satellites is their ability to operate regardless of weather or lighting conditions. In contrast to optical sensors, which are limited by clouds, haze, or darkness, SAR can penetrate these barriers, making it suitable for imaging in areas with frequent cloud cover or at night.
SAR imagery is used for mapping land cover, monitoring vegetation, and detecting changes in ecosystems. It contributes to the monitoring of deforestation, coastal erosion, and land subsidence. SAR can also detect oil spills and help with natural disaster assessments such as floods and earthquakes. SAR satellites have military applications such as surveillance, reconnaissance, and strategic terrain mapping. They are capable of detecting and tracking moving objects, monitoring border areas, and providing situational awareness in remote or hostile environments. Bridges, dams, pipelines, and roads are among the infrastructures monitored by SAR satellites. They can detect ground deformation and subsidence, identify potential hazards, and aid in structural integrity assessment.
