摘要
针对雷达目标互易性修正问题 ,从极化测量误差模型出发 ,提出了基于最小变质准则的散射矩阵修正方法 .经过推导 ,把一个四维带约束非线性最优化问题转化为一个二维无约束非线性最优化问题 ,并给出了求解过程 .最后通过仿真实验比较了最小变质修正法和Cameron修正法的性能 。
With the analysis of polarimetric measurement error model, a novel correction algorithm on radar target's reciprocity is presented based on least degradation rule. After transforming the nonlinear optimal problem of four degrees of freedom with constraints to a nonlinear optimal problem of two degrees of freedom without constraints, the solution is given. Simulation results verify its feasibility and indicate its good performance.
