摘要: |
针对箔条干扰时目标与干扰难以区分的问题,设计了一种基于多特征向量的分类算法。该算法首先对目标和箔条的特征进行分析,而后选择并构造了一组具有较高区分度的极化特征识别量,最后采用支持向量机(SVM)方法,通过对特征样本进行训练,获得了较好的分类结果。实验表明,所提算法具有较强的抗箔条干扰能力,且检测正确率可达90%以上。 |

Abstract: |
Chaff interference can bring many difficulties in target detection. Addressing on this problem, a classification algorithm is proposed in this paper. The multi-features of targets and chaffs are analyzed and extracted firstly.Then, a polarized eigenvector is designed.Finally, support vector machine(SVM) approach is applied and through data training,good classification results are achieved. The simulation results demonstrate that the proposed method has good anti-chaff -interference ability and the correct detection probability is greater than 90% at most time. |
