基于激光半主动的弹道修正系统修正能力的研究

弹道修正技术是为了解决射程与精度的矛盾而采用的一种有效方法。激光半主动弹道修正是采用激光半主动检测落点误差,通过对鸭舵进行弹道修正来提高打击精度的。分析了激光半主动弹道修正系统的工作原理和尾翼式微旋火箭弹鸭舵执行机构控制力,建立了尾翼式微旋火箭弹的刚体弹道,在最大周期平均控制力下持续对由弹道修正的弹道修正能力进行了仿真,得到不同启控时间的弹道修正能力。为激光目标指示器、探测器、鸭舵执行机构协调设计提供了理论依据。

Study on the correction capability of the trajectory correction systenl based on semi-active laser

The trajectory correction technique is an effective method to solve the contradiction of range and precision,the trajectory correction of semi-active laser uses the semi-active laser to test the trajectory terminal error and the canards to correct trajectory for enhancing the striking precision.The principle of semi-active laser trajectory correction system and the control force by canards are analyzed.The 6-DOF trajectory model of rocket projectile is established,the correction capability is simulated in the most periodic average control force.Simulation results indicate the relation between the control starting point and the correction capability.The results supply a theoretical basis for the harmony design of the laser target indicator and the detector and the canard mechanism.
