【摘要】 以陕西省宜川县三北防护林地区获取的航天飞机成像雷达ＳＩＲ－Ｃ／Ｘ－ＳＡＲ数据为基础，进行了森林类型的识别与分类， 区分出针叶林、阔叶林和混交林３ 种森林类型．并通过从ＳＩＲ－Ｃ／Ｘ－ＳＡＲ数据中提取这３ 种类型森林的后向散射系数， 分析了多波段、多极化雷达在森林类型识别中的作用．更多还原

【Abstract】 The paper presents the results of discrimination and classification of Three North shelter forests using shuttle imaging radar (SIR C/X SAR) data in Yichuan count, Shannxi province. The forest is divided into three types: coniferous, deciduous and mixed forest. The backscatter coefficients of three forest types are extracted from the SIR C/X SAR data, and the effect of the forest types discrimination is analyzed using multifrequency and multipolarization.更多还原
