摘　　要：对于矢量测量极化雷达,针对杂波背景下目标极化散射矢量最优估计问题,以最小化目标散射矢量估计的均方误差为准则,设计了基于发射极化优化的目标散射矢量最优估计问题形式,提出了一种基于序贯估计的发射极化优化算法。数值仿真试验验证了算法的有效性,证明了极化雷达发射极化优化较固定极化设计的性能优势。As to polarimetric radars with vector measurement, the optimal estimation of the target scattering vector under clutter background is studied. Taking the minimized mean square error of the target scattering vector estimation as the criterion, the optimal estimation to the scattering vector based on transmit polarization optimization is formulated. An algorithm is proposed to optimize the transmit polarization based on sequential estimation scheme. Numerical simulation results demonstrate the effectiveness of the proposed algorithm, and show that the performance of transmit polarization optimization is superior to that of the conventional polarization design.
