Three-dimensional Radar imaging of distributed media

Synthetic Aperture Radar (SAR) Tomography (TomoSAR) is a microwave imaging technology to recover the 3D structure of the illuminated scene by flying a Radar sensor along multiple trajectories. At microwave regime, electromagnetic waves are capable of penetrating into natural media that are non-transparent at optical frequencies, for example vegetation, snow, ice, and sand. This feature makes TomoSAR sensitive to the vertical structure of those media, hence providing a substantial advantage over optical sensors.

The downside is that TomoSAR signal processing involves a number of challenging aspects as compared to conventional 2D SAR focusing, such as: 3D migration, focusing in the presence of propagation velocity variations, sub-wavelength data-based retrieval of platform position.

The aim of this talk is to present different aspects relative to tomographic SAR imaging and its applications, such as:

  • Basic imaging principles
  • Advanced signal processing
  • Polarimetry & Tomography
  • Added value for forestry, snow-pack and glacier remote sensing
  • Possibilities for spaceborne tomography¬†
