Three-dimensional Building Layout Imaging Based on Bistatic Radar

This paper deals with a problem of three-dimensional building layout imaging exploiting a narrow-band narrow-beam bistatic radar. We propose a novel joint land-to-air scanning manner for the building layout sensing by employing a ground-based transmitter and air-based receivers. Specifically, we first use WKB approximation to establish the relationship between the received signal and the unknown geometric layout. After that, an iterative reconstruction algorithm combining the algebra reconstruction technique (ART), total variation (TV) minimization and median filtering (MF) method is developed to reconstruct the layout with a high quality. Finally, simulation results validate the effectiveness of the proposed method with less than 3% measurements.
