摘　　要：黄河主溜线的提取可为防洪堤的设计、管理以及防灾决策等提供科学可靠的依据,对黄河的生态环境建设、治理和堤岸的稳固也都具有十分重要的意义。这里利用SAR全天候、全天时成像的优势,依据主溜区与非主溜区波浪差异的物理特性,基于现代谱估计方法提出了一种黄河主溜线的提取方法。通过实际SAR数据实验,验证了算法的有效性。The extraction of Yellow River mainstream line can provide a reliable scientific basis for the design of anti-flood,disaster prevention and management,and decision-making.It is also of great significance for the Yellow River on the ecological environment,governance and the stability of the embankment.Taking advantage of SAR all-weather,all-day imaging,according to the mainstream area and the non-mainstream area differences in physical characteristics of waves,a method is proposed which is extracted Yellow River mainstream line by using modern spectral estimation technology.The SAR data experiments show that the algorithm is effective.
