摘　　要：提出利用全极化格雷互补码探地雷达结合H-Alpha极化分解技术,实现对地下目标快速准确地识别。所提方法采用具有零旁瓣特性的格雷互补码信号作为探测信号,用来提高系统信噪比;采用全极化探测模式,获取比单极化探测方式更丰富的目标信息;对采集到的全极化雷达数据进行H-Alpha极化分解,最终实现不同目标的分类识别。实验结果表明:所提方法能够有效识别出地下不同极化属性的目标。进一步,研究了多目标场景中其他目标的存在对目标分类识别的影响,结果表明:当地下存在相同极化属性的目标体时,不会对目标的分类结果造成影响。而当存在不同极化属性目标体时,在分类模板上目标的分类结果会受另一目标极化属性的影响而发生偏移。尽管如此,不同属性目标数据点依然主要集中在指定区域,依旧可以识别出目标。Combined full polarimetric Golay complementary coded GPR with the H-Alpha decomposition technique,a method to accu-rately and quickly identified underground targets is proposed.The proposed method utilizes Golay complementary codes with zero side-lobe as the probe signals,which can improve the signal-to-noise ratio of the radar system.By using the full polarization detection mode,more target information can be obtained than in the single polarization detection mode.After applying the H-Alpha decomposition tech-nique to process the full polarimetric radar data,the classification and identification of different targets are achieved.The experimental results show that the proposed method can effectively identify underground targets with different polarizations.Additionally,in a multi-target scene,the effect of the presence of other objects on target recognition is investigated.The results show that when there are targets with the same polarimetric attributes,the target classification results are not affected.In contrast,when there are targets with different polarimetric attributes,one of the target classification results on the template is shifted towards another.Nevertheless,the data points of targets with different polarimetric attributes are still mainly concentrated in the specified area,and the targets can also be identified.
