| 摘 要： | 近年来合成孔径雷达(SAR)技术得到快速发展,它通过飞行平台的向前运动来实现合成孔径。它的穿透特性使它获取的影像基本不受云、雾的影响,而且能够透过地表和植被获取地表以下信息。最初用于军事上探测空中和地面的运动目标,后来逐渐应用到农业、林业、地质、环境、水文、灾害、测绘等领域。文中主要介绍合成孔径雷达技术的特点及其在森林资源调查、森林分类、自然灾害监测、森林蓄积量和生物量估测、土地利用分类、土壤水份估测等林业中的应用现状,对合成孔径雷达技术在林业中的应用前景进行了展望。

| Abstract: | In recent years,synthetic aperture radar（ SAR） has been rapidly developed,which realizes synthetic aperture through the forward movement of the flying platform. Its penetrating characters are not affected by cloud or fog to obtain images and penetrate the surface of the earth and vegetations to get information below the earth. Originally,it is used in military to detect air and ground moving targets and then gradually applied to agriculture,forestry,geology,environment,hydrology,disasters,surveying and mapping and so on. This paper introduces the characteristics of SAR,and its application status in forest resources survey,forest classification,natural disaster monitoring,forest volume and biomass estimation,land use classification and soil moisture estimation etc.,Future SAR application in forestry sector has been prospected. |
