中文摘要：
对InSAR干涉条纹图的形成进行了研究，基于星载InSAR的空间几何关系及雷达成像的特点给出了InSAR的干涉图模拟模型和计算公式。将条纹频率分析的相位展开方法应用于我们给出的干涉图模型，得到了很好的相位展开结果。条纹频率分析产生可靠性模板，基于该模板的排序算法将误差范围控制在局部最小的区域。
英文摘要：
Foormation of InSAR（Interferometric SAR） inteferometry fringe is simulated, and InSAR interference pattern simulation model and computation formula are given, based on geometry relation of spacebome synthetic aperture radar interferometry and charactors of radar imaging. Phase unwrapping algorithm based on the fringe frequeney analysis is applied to the interference pattern simulation model. We obtain the good result. Reliability mask is produced by the analsis of fringe frequency. Thegn the error is limited to local minimum areas by using the ordering algorithm based on the reliability mask makes.
