This paper concerns the theoretical analyzing about the information capacity and characteristics of the echo's polarimetric components, in through-the-wall scene, resorting to the polarimetric scatter matrix. The expressions of the four polarimetric components are proposed. Based on the reasoning, we deeply analyze the characteristics of each component and its effect on the imaging, detection and further process. Then some suggestions about optimal application of the polarimetric components are given. Experiment results validate this paper. What's more, the reasoning, in this paper, also applies to other signal format after simple transformation.

“…Increasing attention has been paid to imaging of a building [1][2][3][4][5][6][7][8][9] , which can provide building layouts and insurgent activity profiles. Bistatic SAR through-wall imaging is a promising new aspect in through-wall sensing, Bistatic radar provides greater diversity in aspect angle than monostatic radar and acquiring more scattering information, which is competent for imaging of a building [1][2][3].…”

In the BiSAR (Bistatic Synthetic Aperture Radar) through wall imaging system, effective imaging algorithm is of great importance. Back Projection (BP) algorithm can serve almost all cases with good precision. A bistatic configuration with a stationary receiver and a side-looking vehicleborne transmitter has been designed for through wall imaging in this paper. BP algorithm in this case is developed. The range, Doppler and azimuth resolution formulations are deuced. Imagings of a room with targets in it are simulated, and resolution distributions of the scene under different bistatic configuration are simulated too. it is found out that the bistatic angle affects the imaging of a scene. Simulation results and the theoretical analysis can be reference for bistatic through wall SAR imaging.

In order to reconstruct the building interior layout from the through-the-wall radar image, this paper proposes a method based on minimum spanning tree (MST) which comes from the graph theory. The building layout graph (BLG) model is firstly established using the wall-wall-floor trihedrals inside the building. The vertex set and the edge set including the weight between any two nodes of the graph are defined afterwards. Then, the MST-based method is used to reconstruct the building interior layout. We have also improved the traditional method by applying the MST model with restricted conditions to solve the reconstruction problem when there exist interference targets in a building. The anechoic chamber measurements are carried out to demonstrate the suitability and efficacy of the MST-based method.
