摘要
为提高火箭助飞鱼雷关机点计算速度,基于Chebyshev多项式拟合了火箭助飞鱼雷关机方程,可根据不同的射程快速解算助飞鱼雷关机点,实时控制射程。与常用的摄动制导关机方法相比,计算简洁、迅速。并对火箭助飞鱼雷进行了仿真计算,证明该方法可满足落点精度要求。
In order to in prove computing speed of burn-out of rocket-assisted torpedo, a new calculating approach calculate shutoff points quickly according to a variety of ranges of the rocket-assisted torpedo so as to control the ranges immediately based on curve fitting of Chebyshev polynomial. Compar with traditional disturbance guidance law, this caculations is easy and quick. Finally the feasibility of this approach was proven by simulation as for the precision of the falling points.
