| 摘 要： | 本文针对转台模式的近场微波成像进行了实验研究。首先介绍了近场微波成像的实验系统，然后考虑到宽频带天线的非理想特性，提出一种近场微波成像系统的实验修正模型。最后基于该模型，给出了利用理想导体长方柱、理想导体圆柱、理想导体正方体盒以及四尾翼导弹模型的实测数据的重建图像。重建图像基本反映了目标的轮廊。

| Abstract: | Experimental studies on the near field microwave imaging by means of radar turntable mode has been done At beginning,an experimental system of the near field microwave imaging is described Then a modified model taking non ideal broad band antenna into account is proposed Based on the model and measured data,some examples of imaging reconstruction are presented,which include perfectly conducting square and circular cylinders,perfectly conducting square box and a model missile with fourtaiplane The reconstruction of images basically depicts the target profile |
