Résumé

This paper presents a new software for design of through-the-wall imaging radars. The first part describes the evolution of a ray tracing simulator, originally designed for propagation of narrowband signals, and then for ultra-wideband signals. This simulator allows to obtain temporal channel response to a wide-band emitter (3 GHz to 10 GHz). An experimental method is also described to identify the propagation paths. Results of simulation were compared to results of propagation experiments under the same conditions. Different configurations were tested and the results were discussed. Finally, a configuration of through-the-wall imaging radar was tested, with different antennas patterns and different targets. Simulated images will be helpful for understanding the experiment obtained images.
