Near field radar imaging in the frequency domain with application to patient data

Radar imaging in the near field for biological applications has received considerable attention in recent years. Development of this new modality is motivated by differences in the dielectric properties of tissues; in particular, cancerous breast tissue has been found to be significantly different from healthy tissues (M. Lazebnik et al, Phys. Med. and Bio., 52(20), 6093115. 2007). These differences cause scattering of electromagnetic fields and by recording the scattered signals at many antenna positions, the locations of high contrast objects can be determined via image formation.
