电磁成像是由物体产生的电磁波动,在观测处形成的反映空间和物体电磁特性的映像。基于电磁反演计算的超宽带无源电磁成像采用超宽带被动式天线阵面获取空间中的电磁信息,利用信息处理算法完成电磁辐射源特征的提取,基于电磁反演计算方法完成对电磁场空间分布的计算,将电磁场和目标三维态势绘制显示出来,能直观、全面地呈现出空间中的电磁分布。

The electromagnetic (EM) imaging is the image of the space and the EM characteristics of the object in the observation position, reflecting the EM wave caused by the object. The ultra-wideband passive EM imaging technology based on the EM inverse computation is to obtain the EM information in the space using the ultra-wideband passive antenna array, and to extract the EM characteristics using the information procession algorithm. Then computing the EM field distribution using the EM inverse algorithm, and displaying the three-dimensional situation of EM field and the object, and directly, wholly presenting the EM situation.
