    摘要:

    干涉合成孔径雷达是获取场景数字高程模型和正射影像图的有效技术之一。叠掩现象是SAR图像几何失真现象的一种。由于多点回波叠加,叠掩区域的相位并不准确,而且在相位解缠中影响判别,因此对叠掩区域进行识别具有重要意义。本文分析了叠掩区域的干涉相位特性及幅度特性,提出了一种结合SAR幅度图像和干涉相位对叠掩区域进行识别的算法,该算法能够有效的将叠掩区域区分出来,为InSAR后续处理提供可靠依据。仿真数据的处理结果,证明了算法的有效性。

    Abstract:

    Interferometric Synthetic Aperture Radar is an effective technique to get Digital Elevation Model and ortho-photo map. Layover is one of SAR geometric distortion. The interferometric phase of layover region is not accurate due to the superposition of multi-echo, it makes the discrimination difficult in phase unwrapping. This paper analyzed the SAR image amplitude and interferometric phase characteristic of layover region, based on which an algorithm is present for detecting layover regions. This algorithm can effectively distinguish layover regions and provide reliable basis for InSAR processing. Simulation experiments results show effectiveness of this algorithm.
