针对低伸弹道复杂环境下对坦克反应装甲的精准定距问题,提出基于电容与磁复合的坦克目标探测方法,其中,电容探测进行精确定距,磁探测进行坦克铁磁目标识别,复合体制解决低伸弹道复杂背景环境的干扰问题。理论分析电容探测原理,通过COMSOL仿真对双电极电容探测模型的电极分布进行优化,有效提高了作用精度。理论推导坦克磁场计算式,对坦克目标周围磁场强度特性进行仿真,基于隧道磁阻设计磁探测电路并进行了实验验证;设计基于状态机的电容与磁复合目标探测识别方法,利用多特征量提高了对目标的识别准确性。开展样机实验验证,结果表明,该复合探测方法可实现对坦克目标的准确识别,达到了1 m ± 0.2 m的定距要求。同时针对对抗四代以上反应装甲探测距离不足的问题,设计单电极自电容探测模型及电路,进行仿真分析,结果表明,探测距离可提高至2 m以上。 |

For the problem of accurate distance measurement of tank reactive armor in complex environment with low extension trajectory,a tank target detection method based on capacitance/magnetic combination is proposed, in which the distance is accurately determined through the capacitance detection,and the ferromagnetic target is identified through the magnetic detection. The composite system is used to solve the interference problem of the complex background environment of the low extension trajectory. The principle of capacitance detection is theoretically analyzed. The electrode distribution of the dual-electrode capacitance detection model is optimized through COMSOL simulation,which effectively improves the accuracy of capacitance detection. The calculation formula of tank magnetic field is theoretically deduced,and the change curve of the magnetic field intensity around the tank target is simulated. The tunnel magnetoresistance is used to design a magnetic detection circuit,which is verified by experiment. A capacitive/magnetic composite target detection and recognition method based on the state machine method is proposed,and the multiple feature quantities are used to improve the target recognition accuracy of fuze. The experimental verification of prototype was made. The result shows that the composite detection method can realize the accurate recognition of ferromagnetic target and meet the fixed distance requirements. At the same time, for the problem of insufficient detection range of the latest reactive armors,a single-electrode detection model is proposed,which can effectively increase the detection range to 2 m through simulation analysis. |
