[Abstract]:The scattering intensity of the target scatterer received by the receiving antenna depends on the position of the target relative to the receiving antenna, the electrical performance parameters of the target and the geometry of the target. In this paper, a target alignment framework is proposed to align the target in different positions to the reference position. Starting with the relationship between the BP (Back Projection) algorithm and the linear Bonn approximation (Born Approximation,BA) inverse scattering mathematical model of electromagnetic field, and combining with the modified Green function design, the de-correlation mathematical model with multiple parameter coupling constraints for the target features is derived. Based on the electromagnetic field simulation data, the effectiveness of the proposed target alignment framework is verified from both qualitative and quantitative aspects.
