高分辨率SAR数据在土地利用监测中的应用研究

随着高分辨率SAR卫星的陆续发射,其全天时、全天候、高效、准确获取地表数据的能力日益展现出明显的优势。在当前土地资源管理不断要求加快监测周期、扩大应用领域、提高监测成效的紧迫形式下,对SAR数据的深入研究与工程化应用已成为当务之急。本文以土地利用的监测实践为依据,系统分析了SAR传感器的数据基础、影像特征和基于实际应用而需要继续拓展的研究领域。

Application of High Resolution SAR Data in Land Use Monitoring

After the successive launches of high-resolution SAR satellites,their advantages of real-time, effective and precise data acquisition have become quite obvious.In accordance with the demand of accelerating the monitoring cycle,expanding application field and improving the effects in land resource management,it is urgenl to conduct a in-depth research of SAR data and put it into engineering application.This paper aims to systematically analyze the data basis of SAR sensors,image characteristics and other possible fields for the practical applications.
