研究了毫米波高分辨雷达杂波环境中的目标检测问题，提出了基于Stokes矢量的高分辨极化目标检测方法，利用毫米波形固有的径向高分辨力对目标进行一维距离成像，结合目标所占据分辨单元区间内的Stokes矢量的幅值以及其极化状态相对于杂波所对应分辨单元内的Stokes矢量的幅值以及其极化状态有着较大的变化这一客观事实，提出了基于Stokes矢量的双门限非参数检测方法，实验仿真结果表明本文方法能够有效改善雷达的检测性能。“,”The problem of target detection in the cluttered circumstance with wide-band high-resolution radar is studied. A high-resolution polarization target detection method based on Stokes vector is presented. With the intrinsic high resolution of wide-band waveform, one-dimension range profile of radar target can be obtained. In connection with the fact that the values of Stokes vector and polarization attitude of target great differ from which of cluttered circumstance, a new target detection method is presented. Simulation experiment results show that radar′s detection perofmance can be improved significantly by using the algorithm presented in this paper.
