Abstract

During the last decades, we have witnessed a widespread deployment of the ultra wide band (UWB) radar systems. Considering a medical field, an algorithm optimizing these systems is pointed out in this contribution. Beginning with the description of the UWB radar system, this algorithm has proved to be not only able to take a medical image of the human body but also capable of diverting the human tissue. Moreover, we insist on the fact that this algorithm can easily optimize different radar parameters. So, the human body layer width, the incident angle and the frequency maximizing reflection coefficient are estimated in this paper.
