摘要
根据SAR干涉原理,提出基于牛顿迭代法的干涉SAR基线估计算法,利用1996年4月15日和16日的ERS-1/2C波段的单视复数据,用该算法求得的基线值和用从欧洲空间局(ESA)的有关基线数据库中查到该景干涉雷达数据相应的基线值分别进行去平地相位的实验,证明基于牛顿迭代法的干涉SAR基线估计提取的基线参数比较精确。
Based on the principle of interferometric SAR, the baseline estimate of interferometric SAP, based on Newton iteration method is provided. The issue of baseline computation can be examined using the ERS-1/2 C wavelength single look complex(SLC) of April 15 and 16 in 1996, and the baseline parameter is estimated by using this algorithm. The flatten phase removal trial is implemented by the baseline, compared with the baseline parameters extracted from ESA. The result indicates this method is accurate.
