Location algorithm and simulation verification of warhead penetrating multi-storey building

针对导弹战斗部攻击多层建筑物目标时,目标内部着靶点位置难以精确测量问题,开展了基于TDOA、单直角阵列和双直角阵列3种定位算法模型的对比分析研究,获得了目标位置精确计算关系式及目标距离较远时的缩略计算关系式,分析了2种直角阵列的定位误差;建立有限元仿真分析模型,获取战斗部侵彻多层框架结构建筑物过程中关键点的振动数据,在此数据的基础上,验证了3种定位算法的定位精度,结果表明:TDOA算法的定位结果与真实值的偏差最小,双直角阵列定位算法的定位结果次之,单直角阵列定位算法的定位结果与真实值的偏差最大。

Aiming at the difficulty to accurately measure the landing position of the missile warhead when it attacks the multi-storey building target,a comparative analysis and research based on different positioning algorithm models were carried out,combined with the position principles of TDOA,single right angle array and double right angle array.The accurate calculation relationship of the target position and the abbreviated calculation relationship when the target is far away were obtained,and the positioning errors of the two right angle arrays were analyzed;The finite element simulation analysis model was established to obtain the vibration data of key points in the process of warhead penetrating multi-storey frame structure buildings.Based on this data,the positioning accuracy of the three positioning algorithms was verified.The results show that the deviation between the positioning results of TDOA algorithm and the real value is the smallest,the positioning result of double right angle array positioning algorithm is the second,and the deviation between the positioning result of single right angle array positioning algorithm and the real value is the largest.
