| 摘 要： | 针对空中目标作大机动时导弹制导误差难以预测的缺点,将导弹和目标视为一个结构随机跳变系统,并将目标作大机动当作系统的外部扰动输入,建立了该系统的数学模型,应用结构随机跳变系统理论对脱靶量的数学期望和方差进行了计算。通过仿真表明,该方法可对大机动目标进行制导误差预测,还可为变系数导引律的设计提供依据。

| Abstract: | Considering that it's difficult to predict the guidance error about those targets with high acceleration,an integrated model is built based on stochastic jump system theory of the missile and the target and views high acceleration of the target as the input variable.Besides,expected value and variance about miss distance are calculated on the basis of the stochastic jump system theory.The simulation show that the method can offer a shortcut for predicting guidance error about those targets with high acceler... |
