摘要: 雷达干涉测量相干性信息对于水域非常敏感.采用阈值异或算法,利用多幅雷达影像计算的相干性图有效提取了青藏高原色林措等湖泊的边界线.通过与光学遥感影像比较,证明相干性信息在精确提取区域性水域范围方面能够发挥重要作用.

关键词: 雷达干涉测量;相干性;湖泊水域范围提取

Abstract: InSAR coherence is very low in the watershed area. The TXOR algorithm and multiple radar coherence images were used to identify the lake boundaries near Siling Co in Tibet. The comparison between the InSAR extracted boundaries and the optical images demonstrates that the method is useful in extracting watershed areas on a large scale.

Key words: Interferometric synthetic aperture radar(InSAR); coherence; lake boundary identification
