| 摘 要： | 应用随机过程及成型滤波器的理论知识,构建了目标随机机动及过程噪声模型,建立了基于过程噪声与测量噪声的增强型比例导引工程应用模型,设计了卡尔曼滤波器来估计系统状态,引入蒙特卡洛法计算脱靶量均方差.通过仿真,分析了采用过载驾驶仪的增强型比例导引系统不同的制导性能指标,并与比例导引制导律进行对比分析,结果表明,测量噪声较大时APN对噪声的抑制效果好于PN,这为增强型比例导引的工程应用提供了依据.

| Abstract: | Applying random process and shaping filter theories,the random manoeuvre model of target was constructed,and the plant noise model was also established.Based on the plant noise and the measurement noise,augmented proportional navigation(APN) engineering model was formed.Kalman filter was designed to estimate the system states,and Monte Carlo method was used to compute the standard deviation of miss distance.The different guidance performance indices of APN system with overload pilot were analyzed.The perfor... |
