Scanning Inside Volcanoes with Synthetic Aperture Radar Echography Tomographic Doppler Imaging

A problem with synthetic aperture radars (SARs) is that due to the poor penetrating action of electromagnetic waves within solid bodies, ability see through distributed targets precluded. In this context, indeed, imaging only possible for on scene surface. This work describes an method based analysis micro-motions present in volcanoes and generated by Earth’s underground heat. Processing coherent vibrational information embedded a single SAR image, single-look-complex configuration, sound exploited, tomographic over depth about 3 km from Measurement results are calculated processing image COSMO-SkyMed Second Generation satellite constellation Vesuvius.
