电磁超宽带（UWB）传感和成像为早期乳腺癌检测提供了前景。本文论述了真实的测量的实际挑战。我们提出了一种基于M序列雷达技术和短有源偶极天线的乳房模型试验的实验装置。它结合了短脉冲响应，适当的保真度和非常小的天线尺寸，并允许在乳房周围具有足够数量的天线的阵列结构。给出了基本方法和成像结果。此外，在此扩展的纸版本的持续发展的步骤进行了描述和测量结果反映具体的性能方面进行了讨论。
Electromagnetic ultra-wideband (UWB) sensing and imaging provide perspectives for early-stage breast cancer detection. This paper deals with practical challenges of real measurements. We present an experimental setup for breast phantom trials based on M-sequence radar technology and short active dipole antennas. It combines short impulse responses, appropriate fidelity and very small antenna dimension and allows array construction with sufficient number of antennas around the breast. The basic approach and obtained imaging results are presented. Furthermore, in this extended paper version continuative development steps are described and measurement results reflecting specific performance aspects are discussed.
