摘要 通过采用时域有限差分方法探讨了一种收发天线分离的早期乳腺癌超宽带微波成像检测方案。在收发共用的超宽带天线设计中要求天线的终端反射不超过-120dB,而采用收发天线分离方案则避免了这一苛刻要求。采用共焦成像算法给出的成像结果表明,该方案亦可探测直径10mm以下的早期乳腺肿瘤。 An ultra-wideband (UWB) microwave imaging scheme with separated transmitting and receiving antennas was investigated by using finite difference time domain method (FDTD). The use of separated transmitting and receiving antennas allows to avoid the critical requirment for the reflection of the antenna terminal, as required in the system with duplex UWB antenna. Imaging results by using the confocal imaging algorithm demonstrate the feasibility of the scheme in the detection of early breast cancer of radius smaller than 10mm.
