| 摘要: |
| 针对导弹防御中可能出现的有源假目标欺骗干扰，从雷达数据处理的层次上进行了真假目标鉴别研究。利用自由段有源假目标与实体目标在动力学模型上的本质差异，提出了动力学模型匹配系数的概念，推导出理想条件下的动力学模型匹配系数的解析表达式。在弹道目标跟踪的基础上设计了有源假目标鉴别算法。结合中程弹道，进行了真假目标鉴别的计算机仿真实验。实验结果表明，所提算法能有效鉴别有源假目标。 |

| Abstract: |
| The problem of discriminating active decoys and radar target was studied based on the radar data processing in the background of missile defense. On the basis of the essential difference of the dynamic model between those active decoys and the real target, the concept of dynamic model match coefficient was proposed. The analytic expression of the coefficient was presented without considering the radar measurement noise. The discrimination threshold was designed based on the radar tracking data. The computer simulation was carried out with the background of an intermediate range ballistic trajectory. The feasibility and validity of the proposed algorithm was verified by the simulation results. |
