摘　　要：针对实数单极化高分辨率一维距离像(high resolution range profile,HRRP)缺失了目标的极化信息和相位信息的问题,研究了复数全极化HRRP目标特征提取方法,为合理有效运用所提取的目标信息,提出一种基于Bagging的选择性集成算法,并在此基础上设计了复数全极化HRRP目标识别方法,最后通过实验验证该方法具有良好的稳健性和可分性。As to the absence of polarization and phase information for real single-polarized high resolution range profile （HRRP）, the feature extraction for complex multi-polarized HRRP is discussed. A novel selective ensemble approach based on Bagging is proposed to use the extracted target information efficiently and properly. Then the target recognition method based on complex multi-polarized HRRP is constructed. The experimental results on measured data indicate that the presented method has a good classification ability and robustness.
