New method of scatterers association and 3D reconstruction based on multi-hypothesis tracking

Aiming at the problems of associating radar target scattering centers from the unknown perspective of one-dimensional range, in order to associate the radar target scattering centers at unknown radar line of sight, a new scatterers association method based on auxiliary information of scatterers intensity using multi-hypothesis tracking (MHT)is proposed. After using the scattering centers intensity information to associate the scattering centers, the target was 3D reconstructed by sequential factorization method. The sequential factorization method can effectively reduce the burden of the data storage and increase the real-time ability. The simulation results verify that the proposed algorithm is simple and very stable for the complex situations. This method can effectively eliminate the false scattering points derived from the process of target moving in the association process of hypothetical update and management, which is applicable to the target in multiple poses multiple scattering correlation and 3D reconstruction. This method has a good robustness for 3D reconstruction of the target under complex spatial motion.
