摘要:雷达遥感具有全天时、全天候监测的能力,对植被具有一定的穿透能力,对植被散射体形状、结构、介电常数敏感;这些特性使得其在农业应用中极具潜力。该文首先介绍了雷达遥感在农业中的应用领域,概略总结了目前在农作物识别与分类、农田土壤水分反演、农作物长势监测等多个领域研究的综述文献;然后分别阐述了雷达散射计和各类SAR特征(包括:SAR后向散射特征、极化特征、干涉特征、层析特征)在农业各领域中应用的现状和取得的研究成果,最后结合农业应用需求和SAR技术发展总结了目前研究中存在的问题和原因,并对未来的发展进行了展望。
Active radar remote sensing technology,with its capability of acquiring all-weather data,has great potential for agricultural monitoring.This technology can penetrate vegetation cover more deeply than optical sensors and has sensitivity to the shapes,structures,and dielectric constants of vegetation scatterers.In this paper,we discuss the applications of radar remote sensing in crop identification,cropland soil moisture inversion,crop growth parameter inversion,crop phenology retrieval,agricultural disaster monitoring,and crop yield estimation.We review several specific papers focusing these fields,and then describe the results obtained using information extracted from radar scatterometers and Synthetic Aperture Radar(SAR).Extracted SAR data include characterizations of backscattering,polarimetry,interferometry,and tomography.Lastly,we summarize the problems faced by radar applications in agriculture and consider the future trend of these applications.
