| 摘 要： | 针对未知和时变的杂波环境,在目标极化状态已知的情况下,探讨了极化域目标识别的问题.在全极化雷达的极化正交的双通道接收系统中,对两路极化正交回波信号进行复加权后与期望信号比较,使其均方误差达到最小,从而抑制了干扰,增强了目标信号.对抑制和增强效果在干扰分别为定极化和变极化的情况进行了仿真,仿真结果表明了该算法的有效性.对此算法中步长因子的取值范围进行了探讨.提取目标极化特征,进行目标识别,并进一步提出识别递推算法.对识别结果进行仿真,仿真结果表明了该方法的有效性. |

| Abstract: | In view of the unknown and the time-varying clutter environment,the target recognition is discussed in a known state of target polarization.For the receiving system with two polarization orthogonal channels,two signals are weighted by complex number and compared with the anticipated signal in order to make the means quare error a minimum by use of polarization adaptation.The interference is inhibited and the target signal is enhanced.For the cases that the clutter polarization state is steady and varying,th... |
