摘要
描述系统运动的状态方程所含的状态量越多 ,其数学模型就越准确 ,但其数字仿真时的算法实现也越困难。因此 ,采用“当前”统计模型建立机动飞行目标的空间运动方程 ,并结合桥函数级数理论求解 ,实现了对机动飞行目标稳定、准确、实时地仿真计算。以典型机动目标为例 ,进行了数字仿真 ,通过对各主要状态量的计算结果分析 ,验证了该方法的有效性。
The more variables of system state equation are described, the more mathematical model will be accurate, and the more realization of digital simulative algorithm difficult, too. This paper presented a method that describes the state equation of maneuvering flying target as current statistical model, connects with bridge function, then realize the digital simulation stable, accurate and in real time. As application of examples, giving the digital simulation of typical maneuvering targets, the calculating result analysis of main states shows convincingly availability of this method.
