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。
UAVs in the process of rapid access to the enemy, the traditional guidance method is very easy to guide the UAV to the enemy's fire within the scope of the attack. Moreover, the optimal solution of the traditional proportional guidance method coefficient is related to the distance between the target and the carrier, and the tracking effect will be worsened if the target maneuver or interference exists. To this end, a data-based UAV variable structure counter attack guidance method is proposed and simulated. The simulation results show that this method not only avoids the attack of the UAV within the firepower of the enemy aircraft, but also reduces the overload required by the UAV, improves the guidance accuracy, speed and robustness, limits the line of sight angular velocity .
