立面结构的语法通常与高分辨率合成孔径雷达（SAR）图像中规则分布的签名模式有关。鉴于图像中的这些模式，它们应该被用作识别与立面相关的变化的信息来源。本文提出了一种方法，用于表征有关定期安排门面结构，制定单方位角/距离SAR图像和地理编码的SAR图像的一般基础上的停留区。该分析遵循对点状特征的强度分布、线性排列和规则性的假设。立面的两个案例研究，这证实了不同的建筑类型的方法的适用性。在此基础上，讨论了该算法在变化检测和持续散射体干涉测量等应用中的潜力和局限性。
The grammar of facade structures is often related to regularly distributed signature patterns in high-resolution synthetic aperture radar (SAR) images. Given those patterns in the imagery, they should be used as a source of information for identifying changes related to the facade. This paper presents a method for characterizing the layover area pertinent to regularly arranged facade structures, formulated on a general basis for single azimuth/range SAR images and geocoded SAR images. The analysis follows assumptions on the intensity distribution, the linear arrangement, and the regularity of point-like signatures. Two case studies on facades are presented, which confirm the applicability of the method for different building types. Based on that, the potentials and limitations of the algorithm are discussed with respect to applications such as change detection and persistent scatterer interferometry.
