Abstract :
The principle and experimental results of bistatic frequency-swept microwave imaging of continuous shape and discrete line conducting objects using simultaneous multi-source illumination are presented. Images of scattering objects reconstructed from the experimental data measured in the frequency range 7.5 GHz to 12.5 GHz are in good agreement with the scattering object geometries. The experimental results show that using multi-source illumination can provide a cost-effective approach for a wider imaging viewing angle and higher resolution of the scattering object.
