3D Scattering Distribution Reconstruction for Air Targets VIA Radar Network

Considering the two-dimensional (2D) imaging result is the map of the target on the imaging plane, the three-dimensional (3D) scattering distribution of the air target is reconstructed by comparing the 2D imaging results and the mapping images in this paper. These 2D images and mapping images are obtained by the radars which are located in different places but have the similar perspectives. Firstly, the mapping formulas are presented briefly. Then the influence of the radar distribution on the scattering distribution reconstruction is analyzed and the radar distribution mode for ensuring the similar perspectives and the scatterers reconstruction performance is established. Finally, the 3D scattering distribution reconstruction method is proposed. In the simulation experiments, the scattering distribution of the target is reconstructed and the validity of the proposed method is verified.
