摘要
为了从有限的观测信息中较准确地获取导弹运动状态信息,针对反舰导弹末段蛇行机动和跃升俯冲攻击等突防方式,利用参数辨识模型动态适应机动目标运动模态变化的特性,实现反舰导弹机动弹道的拟合。通过仿真计算可知,参数辨识模型对蛇行机动和跃升俯冲攻击等运动模式具有较高的拟合精度,算法收敛较快,可为高精度跟踪反舰导弹提供参考。
In order to obtain missile movement status from little observation,the parameter identification model is used to dynamically adapt variety of target＇s maneuvering modes and mimic the piercing terminal trajectory of anti-ship missile,such as snake-wriggling maneuvering and wingover-swoop motion.Simulations show that the algorithm quickly converges and accurately mimics snake-wriggling maneuvering and wingover-swoop motion of target,which is available for improving the precision of tracking anti-ship missile.
