Aim of the project
The development of a complete microwave imaging system, with a frequency bandwidth of 1.87 GHz, ranging from 130 MHz to 2 GHz using time-domain and frequency domain finite volume discretizations of the Maxwell equations which drive a generalized least-squares inversion engine, whose output is a subsurface map of the relative permittivity.
