本文在可控质点系弹道计算分析的基础上,应用最大似然法确定导弹总体、气动和控制装置的随机偏值的统计量,建立了一种仿真导弹射击目标飞行器的数学模拟打靶的随机方法。为了达到较好的仿真效果,除了在弹道计算中考虑目标机动飞行外,并在参数向量中引入了目标机动的随机偏差。利用本文提出的状态误差修正协方差矩阵,在推广卡尔曼滤波中估计导弹与目标之间的最佳极坐标,可以减小导弹的脱靶量.
In this paper, based on the trajectory calculation and analysis of controllable particle system, the maximum likelihood method is used to determine the statistical value of the random partial biased value of missile overall, aerodynamic and control devices, and a stochastic method of simulating the target shooting of the simulated missile is established. . In order to achieve better simulation results, in addition to considering the target maneuvering flight in the ballistic calculation, the target maneuvering random deviation is introduced into the parameter vector. Using the state error correction covariance matrix proposed in this paper, we can estimate the optimal polar coordinates between the missile and the target in the extended Kalman filter, which can reduce the miss distance of the missile.
