全球SAR衛星市場(2023-2033)Global SAR Satellite Market 2023-2033 |
配備合成孔徑雷達 (SAR) 感測器的遙感衛星利用雷達技術捕捉地球表面的高解析度影像。 SAR 衛星使用的微波頻率可以穿透雲層、黑暗,甚至某些類型的植被,這與依賴可見光或紅外光的光學感測器不同。
這就是合成孔徑雷達的工作原理:人造衛星向地球表面發送微波訊號。 SAR 感測器收集反射訊號並測量訊號返回所需的時間。 SAR 衛星可以透過分析返回訊號的相位和幅度來產生地球表面的詳細影像。
SAR衛星可以產生精度達到幾公尺的高解析度影像。 解析度由微波訊號的頻率、天線的尺寸、衛星與目標之間的距離等因素決定。 土地覆蓋、地形、地表變形和隨時間的變化都可以透過 SAR 影像來揭示。
SAR 衛星的主要優點之一是它們可以在任何天氣和照明條件下運作。 與光學感測器受到雲、霧霾和黑暗的限制相比,SAR可以穿透這些障礙,適合在陰天和夜間拍攝。
SAR 影像用於繪製土地覆蓋圖、監測植被並檢測生態系統的變化。 它有助於監測森林砍伐、海岸侵蝕和地面沉降。 SAR 還可以幫助檢測石油洩漏並評估洪水和地震等自然災害。 SAR 衛星也用於軍事應用,例如監視、偵察和戰略地形測繪。 SAR 衛星可以探測和追蹤移動物體、監視邊境地區並提供偏遠地區和敵對環境的態勢感知。 橋樑、水壩、管道、道路等是SAR衛星監測的一些基礎設施。 它可以檢測地面變形和沈降,識別潛在危險,並協助評估結構的健康狀況。

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.
