论文摘要
合成孔径雷达（SAR）的一个问题是，由于固体体内电磁波的穿透性较差，因此无法通过分布式靶标观察的能力。在这种情况下，实际上，仅在目标表面分布的目标上进行成像。这项工作描述了一种基于对火山上存在的微动物的分析，并由地下地下热量产生的成像方法。 处理单个SAR图像中嵌入的相干振动信息，在单程复合配置中，声音信息被利用，穿透性层析成像在距离地球表面约3公里的深度上。测量结果是通过从维苏威乌斯的Cosmo-Skymed第二代卫星星座上处理SLC图像来计算的。 断层图揭示了岩浆室的存在，以及主火山导管。这项技术无疑为全新的SAR图像扫描地球表面扫描的新剥削肯定是铺平道路的。
A problem with synthetic aperture radar (SAR) is that due to the poor penetrating action of electromagnetic waves within solid bodies, the ability to observe through distributed targets is precluded. In this context, indeed, imaging is only possible on targets distribute on the scene surface. This work describes an imaging method based on the analysis of micro-motions present on volcanoes and generated by the underground Earth's heat. Processing the coherent vibrational information embedded on the single SAR image, in the single-look-complex configuration, the sound information is exploited, penetrating tomographic imaging over a depth of about 3 km from the Earth's surface. Measurement results are calculated by processing a SLC image from the COSMO-SkyMed Second Generation satellite constellation of the Vesuvius. Tomographic maps reveal the presence of the magma chamber, together with the main and the secondary volcanic conduits. This technique certainly paves the way for completely new exploitation of SAR images to scan inside the Earth's surface.
