【摘要】：针对接收天线接收的目标散射体的散射强度取决于目标相对于收发天线的位置、目标电性能参数以及目标几何形状的问题,提出一种将不同位置的目标对齐到参考位置的目标对齐框架。该框架创新地从BP(Back Projection)算法与线性波恩近似(Born Approximation,BA)电磁场逆散射数学模型关系入手,结合修正Green函数设计,推导出目标特征受多个参数耦合约束的去相关数学模型。基于电磁场仿真数据,从定性和定量两个角度验证所提出的目标对齐框架的有效性。
[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.
