A multi-view planar near-field scattering tomography system is provided herein. In one aspect the system is developed based on a reformulation of the signal subspace approach utilized for solving the electromagnetic inverse scattering problem. The present invention pertains to a computationally efficient approach to an electromagnetic inverse scattering-based permittivity profile estimation technique. In a second aspect, the system is developed at the millimeter-wave and THz frequency range to ensure accuracy by eliminating the multipath effects and without the need for an anechoic chamber or water as a background medium for clinical, security, and manufacturing applications.
