9706427 Isacks One of the newest and most exciting methods of detecting displacements is through selected aperture radar (SAR) interferometry. This method has been used selectively to identify small displacements over relatively large areas by comparing 'scenes' of the same area made at different times. Displacements of the land surface between the times of the images can then be identified by difference. One of the problems that arises in the method in interference from variable atmospheric conditions. This proposal will explore the application of SAR to an arid region near the Chile-Peru border, where the climate is unusually constant and arid, and where major earthquakes are predicted within the next few years. The results of this study will contribute to the development of the technique, and to an understanding of interseismic strain an a convergent plate boundary region.

9706427 Isacks检测位移的最新和最令人兴奋的方法之一是通过选择孔径雷达（SAR）干涉测量。这种方法已被选择性地用于通过比较在不同时间拍摄的同一区域的“场景”来识别相对较大区域上的小位移。 然后可以通过差异来识别图像的时间之间的陆地表面的位移。在该方法中出现的问题之一是来自可变大气条件的干扰。 这项建议将探讨将合成孔径雷达应用于智利-秘鲁边界附近的干旱地区，该地区气候异常稳定和干旱，预测今后几年内将发生大地震。本研究结果将有助于该技术的发展，并有助于了解会聚板块边界区域的地震间应变。
