介绍了一种基于超宽带微波信号的成像新技术。具体而言，该过程涉及惠更斯原理（HP）;使用HP向前传播波消除了求解逆问题的需要，因此，不需要矩阵生成/求逆。再加上它的简单性，该方法允许捕获的对比度，在何种程度上不同的媒体可以在最终的图像中区分。此外，UWB允许通过组合来自各个频率的信息来利用频域中的所有信息以构建一致的图像。因此，该方法可以识别体积内的显著散射体的存在和位置。通过模拟和测量圆柱体和球体的夹杂物的技术进行了验证。设想所提出的技术应用于医学成像。
A novel technique for imaging based on ultrawideband (UWB) microwave signals is introduced. Specifically, the procedure deals with the Huygens Principle (HP); using HP to forward-propagate the waves removes the need to solve inverse problems and, consequently, no matrix generation/inversion is required. Together with its simplicity, the methodology permits the capture of contrast-the extent to which different media can be discriminated in the final image. Moreover, UWB allows all the information in the frequency domain to be utilized by combining the information from the individual frequencies to construct a consistent image. It follows that the methodology can identify the presence and location of significant scatterers inside a volume. Validation of the technique through both simulations and measurements on cylinder and spheres with inclusions has been performed. Application of the proposed technique to medical imaging is envisaged.
