摘要：

In building layout imaging, the multipath propagation of electromagnetic waves will disturb the received signals, making the result unreliable. To solve this problem, this letter proposes a building layout reconstruction method for wideband tomographic imaging where multipath environments are considered. Specifically, first, we investigate an improved direct-path signals (DPS) delay estimation algorithm, which can effectively suppress the adverse effects of multipath signals. Then, a tomographic projection model is built to map the relationship between the DPS propagation delay and the reconstruction image. In addition, the total variation minimization method is used to reconstruct the building layout. In the end, the effectiveness of the proposed method is verified through simulated and real data.
