Radio Talk- Qualitative Radio Imaging (by Hadi)

Microwave Imaging (MWI) exploits scattered electric fields at the microwave frequency range to explore the region of interest and extract the physical properties. It can be categorized into Quantitative MWI where electrical properties and shape of objects are reconstructed and Qualitative MWI in which only shape is retrieved.

The presentation will include a review of qualitative MWI and its application in industry, namely;

1) Monitoring concrete oil-wells:
In an oil reservoir, the surrounding material can block the perforation of oil through pores of concrete wall into the well. It is shown that the Factorization Method (FM), which belongs to qualitative inverse scattering theory, can be effectively employed to reconstruct subsurface images provided that multi-static electric field measurements are performed inside the well with a circular antenna array

2) Though-the wall imaging (TWI):
The other interesting application of MWI is TWI where inaccessible targets behind the wall can be discovered  by measuring scattered electric fields. A method to decrease the number of transceivers in such scenario will be presented.
