摘　　要：为了推导并设计最佳起爆角和起爆时延算法,研究和分析了基于控制导引一体化(GIF)技术的R-77导弹的弹目交会信息,通过坐标转换和误差去偏,将改进卡尔曼滤波算法应用到弹目交会信息的滤波中,用滤波后的弹目交会信息设计最佳起爆角和最佳时延.根据具体仿真条件进行仿真,结果表明,用改进后的卡尔曼滤波算法对弹目交会信息进行滤波,波动较小,数据较为集中,能得到较高的最佳起爆角和起爆时延估计精度.To deduce and design the optimal burst angle and burst delay algorithm,the information of projectile and target encounter based on R-77 missile of GIF technology was studied and analyzed.According to coordinates conversion and anti-bias of inaccuracy,the improved Kalman filtering was applied in filtering of projectile and target encounter information.By using the filtered information of projectile and target encounter,the optimal burst angle and burst delay algorithm were designed.The simulation result shows that the fluctuation is little while filtering the information of projectile and target encounter by the improved Kalman filtering;the data are concentrated.The high estimation precision of optimal burst angle and burst delay can be obtained.
