Reconstruction of interior layout of building from through‐the‐wall radar image using MST‐based method

Abstract

To reconstruct the interior layout of a building from a through-the-wall radar image, a method based on a minimum spanning tree (MST) which comes from graph theory is proposed. The traditional MST method is introduced and the traditional method is improved by applying the MST model with restricted conditions to solve the reconstruction problem when there exist interference targets in a building. Anechoic chamber measurements are carried out to demonstrate the suitability and efficacy of the MST-based method.
