Abstract

Our goals consist in designing and realizing a Ultra Wide Band (UWB) radar for a medical application. On this basis, we study in this contribution the interaction between the radar's electromagnetic pulse and the human body layer in a UWB frequency range. Indeed, this study helps us to design this radar system and prove the possibility of taking an image of each human body layer by exploiting the several reflected echoes. In fact, we propose an analytic method that enables us to compute the reflected echo by the human body of an oblique incident radar pulse. This new method discards the mutual influence between two adjacent human body layers in order to retrieve a recursive expression that computes the total reflection and transmission coefficients by each human layer. Then, we induce the specific absorption rate of each human body structure. In the same vein, this result enables the designer to estimate the propagation medium of the human body. According to this study, we can realize a UWB radar in an attempt to capture an image of the intern human body structure and detect some dangerous infections like cancer.

人体与超宽带雷达脉冲的相互作用

我们的目标是设计和实现一种用于医疗应用的超宽带雷达。在此基础上，本文研究了超宽带频率范围内雷达电磁脉冲与人体层的相互作用。事实上，这项研究帮助我们设计了这个雷达系统，并证明了通过利用几个反射回波来拍摄每个人体层图像的可能性。实际上，我们提出了一种解析方法，使我们能够计算斜入射雷达脉冲的人体反射回波。该方法不考虑相邻两层人体之间的相互影响，以获取计算每层人体全反射系数和透射系数的递归表达式。然后，我们推导出每个人体结构的比吸收率。同样，这个结果使设计者能够估计人体的传播介质。根据这项研究，我们可以实现一个超宽带雷达，试图捕捉内部人体结构的图像，并检测一些危险的感染，如癌症。
