Abstract :
A recently proposed sensitivity-based microwave imaging algorithm shows good sensitivity and resolution in numerical experiments. Here, the algorithm is applied with measured data from the raster scanning of tissue phantoms. The sensors are two dielectric-filled TEM horn antennas. Images of scatterer(s) embedded in lossy tissue phantoms of thickness 5 cm are successfully obtained using the transmission coefficients acquired in the frequency range from 3 GHz to 10 GHz.
