Knowledge-assisted Building Layout Reconstruction for Through-the-wall Radar Imaging

In this paper, the reconstruction of building layout and interior object is considered only utilizing the attenuation power of transmitted narrow-band signal. More specifically, bistatic radars scan the entire unknown area in the form of tomographic imaging to complete the reconstruction issue. Based on the idea of knowledge assistance, we propose a priori information constrained algebraic reconstruction technology (PIC-ART) algorithm, which presents better performance than current state-of-the-art algorithms in multi-media area. Besides, we first utilize the electromagnetic (EM) simulation software to verify the feasibility of the established model under omnidirectional antennas. The EM simulation results have validated the effectiveness of the proposed algorithm.
