In the work on hand, we propose a 3D propagation model that is useful not only in explaining the mechanisms of wave propagation through the observed area, but also in determining the amplitude and the phase of any given point in the far-zone above the ground. The scenario is composed of two metallic plates representing walls and a 4-in-1 corner reflector, which is located between two walls in Non-Line-Of-Sight (NLOS) areas. This model is based on a Ray-Tracing (RT) technique combined with the asymptotic method Uniform Theory of Diffraction (UTD). Two Ultra-WideBand (UWB) radars are configured as transmitter and receiver in bistatic mode. Furthermore, our model is tested against 33-37GHz (Ka-band) indoor measurements conducted in the anechoic chamber. These comparisons have shown that the model gives a good agreement with the experimental results. Consequently, we have applied the model in order to detect and localize a hidden target as well as generate synthetic data for SAR imaging algorithm. |
