基于远场散射理论，将Radon变换理论引人到远场微波成像领域。给出超宽带雷达信号的概念，提出由超宽带雷达信号散射远场重建理想导体目标简捷的时域成像公式和实现算法。经计算机模拟，实现得到导体球清晰的像，表明该方法是远场雷达成像系统的一种有效方法。

Based on scattering theorem in the far zone, the paper studies the far field microwave imaging with Radon transform theorem. A concept of Ultra wideband radar signal is proposed, and then a time domain imaging algorithm is presented to reconstruct far field images of conducting objects. Numerical results show that the described method can be a cost effective approach in far field microwave imaging systems.
