超音速反舰导弹末端有损飞行弹道分析

Analysis on Terminal Fault Trajectory of Supersonic Anti-Ship Missile

提出了一种导弹有损飞行弹道分析方法。从系统控制的角度出发,考虑导引头和自动驾驶仪一阶和二阶动力学环节,建立了基于矢量方程的三维广义比例导引攻击模型。对于导弹末端突防过程中可能出现的典型故障模式,将其对攻击弹道的影响投射到末制导控制回路中,通过对末制导方程的仿真分析,建立了导弹在典型故障模式下的攻击弹道,给出了脱靶量。

A lossy flight trajectory analysis method was proposed.From perspective of system control,a 3 dimensional true proportional navigation guidance attack model was established in form of vector equation by considering first-order and second-order kinetic characteristics of missile seeker and autopilots separately.For potential failure modes of missile during terminal penetration,by projecting its effect to the guidance and control loop,the attacking ballistic trajectory under different failure modes was obtained with TPN vector equation,and correlative miss distance is offers as well.
