摘　　要：为满足新一代箱式远程制导火箭弹系统及其新型战斗部的需求,对单型炸高可选择近炸引信进行研究.该型引信的炸高覆盖范围大且炸高可选择,既能满足大威力整体战斗部和电磁脉冲战斗部的炸高需求,又能满足子母战斗部的精确定高开舱需求,对提高陆军精确打击能力具有重要的军事价值.为此,提出一种基于毫米波相控阵探测器的炸高解算方法,通过相控阵探测器测高数据与惯性导航数据的融合处理,实时计算火箭弹飞行高程,从而实现炸高控制.并且将融合结果作为惯导的初值来计算下一时刻的惯导测高数据,在一定程度上减少了由于时间积累造成的惯导测量误差,提高了测高精度.仿真实验证明了该方法的有效性和炸高解算精度.In order to meet the burst height requirements of a new generation long-range guided rocket projectile,a novel large dynamic optional burst height fuze based on phased array detector was proposed and analyzed in this paper.Due to the burst height of the proposed single-type fuze was assigned to be larger range,optional burst height,satisfying the burst height of larger power warhead and electromagnetism pulse warhead,adapting the discharge height of composite warhead,improving the precise strike ability for army corps and so on,a burst height calculation method was proposed based on millimeter phased array detector for the optional burst height fuze.Firstly,integrating the height measure data of the phased array detector and the inertial navigation data,the height of the rocket was calculated in real time to realize the burst height control.Then the fusion results were regarded as initial value of inertial navigation height measurement to calculate the height at next moment,reducing the measurement error caused by time accumulation and improving the height measurement accuracy.Simulation results show the validity of the method and the calculation precision of the burst height.
