Description: The Phase Gradient Autofocus (PGA) algorithm
has been widely used in Spotlight Synthetic Aperture
Radar (SAR) to remove motion-induced blurs in the
images. The PGA algorithm has been proven to be a superior
autofocus method. PGA assumes a narrow beam,
which is valid for most SAR systems. However, lower altitude
SA& have large range dependencies that cannot be
ignored. A new phase estimator for PGA is introduced
and extended to allow range dependence. An ERS-1 image
of Death Valley is used in simulations comparing the
new estimator to the widely used maximum likelihood approach
and in demonstrating the range-dependent PGA
algorithm.

Description: 季节性冻融导致的地表形变是冻土地区工程建设的主要病害,冻土的冻胀和融沉是影响青藏
公路以及目前建设的青藏铁路路基稳定的重要因素.近年来,差分干涉测量技术已成为地表形变测量
和监测的重要工具.基于重复轨道的ERS-1/2雷达图像,研究了利用干涉SAR技术探测冻土形变的方
法,经过对引入DEM差分干涉SAR技术的处理和分析,得到研究区冻土形变结果.通过与实测数据
比较,表明重轨差分干涉测量可以精确地探测冻土表面形变,可用于青藏铁路冻土形变监测.
-Seasonal freezing and thawing cause surface deformation is the main disease permafrost area construction projects, permafrost heave and thaw settlement is an important factor in the current construction of the Qinghai-Tibet Highway and Qinghai-Tibet railway embankment stabilizing influence in recent years, the differential interferometry techniques have been surface deformation become an important tool for measuring and monitoring. Repeat track ERS-1/2 radar image based on research using SAR interferometry technique to detect permafrost deformation method, after the introduction DEM differential interferometric SAR technology processing and analysis, research permafrost deformation results by comparison with the measured data, indicate heavy rail differential interferometry can accurately detect permafrost surface deformation, can be used for deformation monitoring permafrost.
