Abstract :
In this paper the influence of multipath propagation on the quality of UWB imagery is analyzed. Typical UWB imaging methods like time domain migration consider only propagation paths with one reflection at the object of interest. In most scenarios the paths of higher order are attenuated sufficiently to neglect them. However, in scenarios containing metallic objects (e.g indoor factory scenarios) multiple reflections can occur without strong attenuation of the signal. In this paper the influence of these multiple reflections on the generated image is investigated.
