Real data microwave imaging using time reversal

Description

The development of SIMIS (Synthetic Impulse Microwave Imaging System), a microwave array of eight ultra-wideband Vivaldi-type ETSA antennas, employed to image unknown targets situated in an anechoic chamber, is presented. Real scattering data, collected via an RF multiplexer interfaced to a vector network analyzer, is imaged using the Time Reversal Method. The imaging algorithm is applied to the scattered field from a dielectric cylinder. In addition, real data is presented for the same dielectric cylinder, located behind a vertical wall.
