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.

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\nthe SIR-C/X-SAR data, and the effect of the forest types discrimination is analyzed using multifrequency and multipolarization.
