| 摘 要： | 本文将ＣＴ原理和雷达转台成像原理引入到近场微波成像领域。作为ＣＴ中背投影响的推广，给出了球背投影的概念，进而提出了由散射近场重建理想导体目标轮廓的球背投影法及其实现算法，计算机模拟结果表明该方法是近场微波成像系统的一种有效方法。

| Abstract: | The paper studies the near-field microwave imaging with the principles of CT and radar turntable imaging introduced. As extension of the back-projection,a concept of spherical back-projection(SBP)is proposed,and then a SBP algorithm is presented to reconstruct near-field microwave images of conducting objects.Numerical results show that the de4scribed method can be a cost-effecttive approach in near-field microwave imaging systems. |
