干涉雷达时间序列分析方法是差分干涉测量技术中的一种新方法,利用高斯马尔可夫模型构建其相位模型,对参数进行估计,需要解决整周相位模糊度问题.因此,将改进的最小均方模糊度去相关调整算法(MLAMBDA算法)引入干涉雷达时间序列分析中求解整周相位模糊度,通过多次实验对比分析,解决了算法应用和软件编写中的关键问题.最后应用在天津地区沉降监测项目中,获得了可靠的沉降监测结果,同时表明MLAMBDA算法在干涉雷达时间序列分析方法中的应用正确有效.

The time series analysis for D-InSAR is a new kind of method.While modeling with Gaussian Markov model and estimating parameters,how to search for integer phase ambiguity needs to be addressed.Therefore,the modified least-squares ambiguity decorrelation adjustment algorithm (MLAMBDA) is applied for the optimal integer phase ambiguity.The main problems about applying and programming are analyzed and solved by many experiments.At last,the method is applied for the project of all Tianjin district and the result is effective,it is also testified that MLAMBDA is correct and effective for the time series analysis in D-InSAR.
