乳腺癌影响了许多女性，及早发现有助于快速有效的治疗。目前最流行的乳腺X光检查方法有一定的局限性，而微波成像提供了一种有吸引力的替代方法，本文介绍了一种利用以前介绍的共焦微波成像技术来检测乳腺肿瘤的微波系统。用超宽带脉冲照射乳房，并使用合成扫描焦点涂料来检测肿瘤：然而，几何配置和算法与以前使用的不同。研究了小天线用于肿瘤检测的可行性。描述了为减少皮肤的主要反射而开发的信号处理算法，并证明了这些皮肤减去算法的有效性。用不同数目的天线重建同质和异质乳腺模型的图像。同时考察了天线间距的影响和简化模型对系统评估的适用性。
Breast cancer affects many women, and early detection aids in fast and effective treatment. Mammography, which is currently the most popular method of breast screening, has some limitations, and microwave imaging offers an attractive alternative, A microwave system for breast tumor detection that uses previously introduced confocal microwave imaging techniques is presented in this paper. The breast is illuminated with an ultrawide-band pulse and a synthetic scan of the focal paint is used to detect tumors: however, the geometric configuration and algorithms are different from those previously used. The feasibility of using small antennas for tumor detection is investigated. Signal processing algorithms developed to mitigate the dominant reflection from the skin are described, and the effectiveness of these skin subtraction algorithms is demonstrated. Images of homogeneous and heterogeneous breast models are reconstructed with various numbers of antennas. Both the influence of antenna spacing and the suitability of simplified models for system evaluation are examined.
