SAR tomography is a remote sensing technique, extending SAR interferometry, that allows three-dimensional imaging of multiple height-distributed point-like scatterers or volumetric targets. It allows, for example, to solve layover urban scatterers or to analyze the vertical structure of vegetation layers or other targets with significant penetration of the sensor's radiation (dry soil, ice layers, etc.). The ability to monitor the 3-D inner structure of volumetric targets and to extract… Expand
