针对InSAR技术在城市重大工程中的应用，提出了一种提取PS（永久散射体）的优化策略。通过综合采用幅度相干性、点目标提取方法来获取高密度、高精度的PS。在此基础上，对PS点的空间分布性进行深入分析，并采用克里金插值弥补分布不足。本文以京津城际数据为例，从区域和线性工程两个角度对上述方法进行实例分析，验证本文PS选择策略和插值方法的有效性。

In this paper ,an advanced strategy for the generation of Permanent Scatter is presented to be used in ur -ban project .The pixel candidates with high density are selected from those presenting low temporal variability of the backscattering or low spectral diversity .Later on,the spatial distribution of the candidates is analyzed ,and the Kriging interpolation is advanced as a complementarity .The selection and interpolation techniques have been tested with Jing-jin high-speed railway from region to linear project .
