Abstract: 

Synthetic aperture radar (SAR) is an active microwave remote sensing technology that can obtain two-dimensional (2D) microwave scattering images. However, due to the influence of equidistant projection and layover problems, SAR images suffer from severe distortion, which affects information interpretation. 

  Interferometric SAR (InSAR) can achieve elevation inversion based on the phase information of the obtained SAR images. As an extension of InSAR, Multi-frequency (MF)/multi-baseline (MB)-InSAR can achieve elevation inversion of steep terrains and solve the problem of elevation ambiguity by increasing the frequency channels or geometric free-degrees. On the basis of MB-InSAR, Tomographic SAR (TomoSAR) can solve the overlapping problem of InSAR and achieve three-dimensional (3D) imaging through the elevation-dimensional equivalent aperture formed by the multiple baselines.

  This session focuses on the research of SAR 3-D imaging technology, including new models, frameworks, algorithms, and applications of 3-D imaging. The related solutions include but are not limited to InSAR, TomoSAR, Circular-SAR, Array SAR, etc. It is committed to solving the technical difficulties of SAR 3D imaging, promoting technical exchanges and application in related directions, and assisting the development of SAR remote sensing technology.
