无人机数据链变结构对抗攻击导引方式研究

UAV Data Links Variable Structure Against Attacks Guidance Law Research

无人机在快速接敌的过程中,传统的导引方法很容易将无人机导引到敌机的火力攻击范围之内。而且传统比例导引法系数的最优解与目标和载机的距离有关,一旦目标机动或存在干扰,跟踪效果都会变差。为此提出了一种基于数据链的无人机变结构对抗攻击导引方式,并进行仿真研究。仿真结果表明,该方法不仅避免把无人机导引到敌机的火力攻击范围之内,而且减小了无人机所需过载,提高了制导精度、速度和鲁棒性,限制了视线角速度。

In the course of UCAV approach to the enemy plane, tradition proportion guidance law is easy to let our plane into the scopes of target fire attack. And the beast coefficient of tradition proportion lead law is related to the target and UCAV＇s distance, If the target moves with high acceleration or is disturbed, the attack result will become bad. For resolving these questions, a method was given based on data link variable structure adaptive opposed guidance law and make a simulation was made, The simulation result shows that the method not only evades guidance ourplane into targetfire attack scope, but also reduces the overload of the UCAV, improves guiding precision, velocity and robust, restricts the line of sight angle＇s speed.
