Human is one kind of the most interesting targets in through-the-wall imaging.
In high-resolution imaging applications, human is no longer a point target.
Therefore, the previous signal models constructed by point target assumption cannot accurately describe real characteristics of EM propagation.
We construct the signal models based on extended target theory in this paper.
Compared with previous works, the main contributions are as follows.
Firstly, human is considered as an extended target.
The expressions of target scattering and wall reflections are derived.
Secondly, target scattering is no longer isotropic in new model.
A new kind of ghost problem which is caused by target obscuring in EM propagation is discovered and exploited.
Thirdly, to improve image quality in moving target imaging, an efficient approach which adopts CFAR, clustering method, and spatial geometry relationship is proposed to remove the ghosts.
The derived models are shown to agree with synthetic and experimental results.
And the efficiency of proposed method is also validated, which illuminates that the ghosts are efficiently mitigated and the image quality is significantly improved.
