A Preliminary Experiment for Microwave Thorax Imaging Based on One-Step Gauss Newton Method

A preliminary experiment for microwave thorax imaging is conducted. A low-profile symmetrical meandering dipole antenna operating at 915MHz is designed and a rectangular water tank with 16 antennas is built for experiments. A graduated cylinder is placed in water as a target. Each antenna in turn acts as transmitter and the others work as receivers. Transmission coefficients are measured. With One-Step Gauss Newton Method, the size and position of the target can be reconstructed. The experiment results verify the feasibility of microwave thorax imaging.
