中文摘要：
将SUSAN滤波算法引入InSAR领域并进行改进,提出基于SUSAN及其改进算法的InSAR干涉图复数域滤波算法。为验证算法的有效性,将SUSAN及改进的SUSAN滤波算法与经典的Goldstein滤波算法进行对比实验,结果表明SUSAN及其改进算法比Goldstein算法优越,在相位奇异点方面对Goldstein算法的改善程度从71.7%提高到82.6%。SUSAN算法,尤其是其改进算法,不仅能较好地抑制干涉图噪声,而且能较好地保留干涉图的边缘信息。
英文摘要：
The SUSAN filtering and its improved algorithm are introduced into for InSAR inteferogram filtering.The effects of the SUSAN and its improved algorithm are compared with that of the Goldstein filter.The experimental results with real data show that the proposed algorithms are superior to Goldstein filter,and make the improvement of 71.7% to 82.6% on Goldstein filter in reducing phase residual.The SUSAN and its improved algorithm,especially the latter,can not only suppress of interference noise better,but also keep the edge information of interferogram.
