【摘要】 工程上实现最佳引战配合要求导弹战斗部最大破片密度方向瞄准目标要害部位。基于一维相控阵引信的波束控制技术,推导了最佳起爆角和起爆延时算法,并研究了一种改进卡尔曼滤波方法在此算法中的应用。该滤波算法将球坐标系中导弹导引头的测量信息转换到直角坐标系下进行滤波,同时消除了由于坐标转换而引起的偏差。仿真结果表明,该滤波算法的应用能得到很高的最佳起爆角和起爆延时估计精度。更多还原

【Abstract】 Optimal fuze coordinate warhead in engineering demands the maximum fraction density direction should aim at target’s key position. Based on beam control technology of one-dimension phased-array fuze, the paper deduced the optimal burst angle and burst delay algorithm and researched an improved Kalman algorithm. The algorithm filtered the information which was converted from polar coordinates to rectangle coordinates. At the same time, it eliminated the divergence caused by coordinate transform. Simulation results indicated that the application of this Kalman filter can get the high estimation precision of optimal burst angle and burst delay.更多还原
