| 摘要: |
| 针对高空高速目标探测过程中可能出现的角度类欺骗有源假目标,从理论上系统地分析了其动力学性质,导出了假目标的动力学方程,并分析了假目标的机械能和动量矩守恒问题。理论分析和仿真试验均表明,具有固定角度欺骗的方位有源假目标其动力学特性和真实目标完全一致,在动力学上是无法鉴别真伪的；除此之外的其他角度类欺骗有源假目标均不满足高空高速目标椭圆轨道特性以及动力学守恒定律,利用这种差异可以在数据处理层对假目标进行鉴别。 |

| Abstract: |
| Aiming at the active angle deception decoys that may appear in the process of high-altitude and high-speed target detection, a comprehensive and theoretical analysis of the dynamics characteristics was presented, the dynamics equation of active decoy was derived, and the conservation of mechanical energy and moment of momentum of the decoy were analyzed. Theoretical analysis and simulation experiments show that the dynamic characteristics of the azimuth active decoy with fixed angle deception are completely consistent with the real target, and it is impossible to distinguish the true from the false in dynamics. In addition, other angle deception active false targets do not meet the elliptic orbit characteristics of high-altitude high-speed targets and the law of conservation of dynamics. This difference can be used to identify the false targets in the data processing layer. |
