合成孔径雷达数据估测森林生物量研究综述

Review of Forest Biomass Estimation Using SAR Data

合成孔径雷达(SAR)技术以其独特的成像机理及其全天候全天时成像能力,在森林生物量估测方面发挥着越来越重要的作用。首先对森林生物量SAR估算机理和方法进行介绍,然后分析主要的影响因素,最后指出今后的发展趋势。

Synthetic Aperture Radar（SAR） ,which has particular imaging mechanism and can acquire data in any time,has become more and more important to estimate forest biomass. In this paper, the mechanism and methods of forest biomass estimation using SAR data were introduced at first. Then, the factors affecting the accuracy of the estimation were discussed. Finally,the trend of forest biomass estimation using SAR data was presented.
