摘要
作为湿地类型较多、分布广泛的国家,中国的城市发展进程在一定程度上对我国丰富的湿地资源形成了很大的威胁,部分湿地遭到破坏。合成孔径雷达(Synthetic Aperture Radar,SAR)作为一种主动式微波遥感,其全天时全天候的特性十分适合湿地的监测工作。然而现在利用SAR进行湿地分类的研究尚未成熟,未能充分使用多个波段的信息分析,本文提出一种利用星载C波段以及机载p波段湿地分类的方法,有效地改善了分类的效果,提高了分类的精度。
As a country which has many wetlands types that wide distributes, the development of cities in China may have a considera- ble threat or damage on the abundant wetland resources. Synthetic Aperture Radar （Synthetic Aperture Radar, SAR） as a kind of ac- tive microwave remote sensing, its ability to monitor all daytime and all weather. But now the wetland classification by using the SAR research has yet to mature, we have not use the multiple wavelengths of information analysis fully, In this paper, a new method which uses space borne C band and airborne p - band wetland classification has been presented, which can effectively improve the classifica- tion effect and improve the classification accuracy.
