摘要
现代空战环境趋于复杂化,而传统方法对于机动目标难以获得理想的导引效果。因此,针对现代无人机空战导引问题,提出了一种基于顶层滚动优化和底层跟踪的空战导引方法。其中,基于高斯伪谱法的顶层优化以时间为性能指标,快速将无人机导引到目标区域,当目标机动时,对其轨迹进行预测并重新优化导引轨迹。此外,引入对导引视线角的底层跟踪方法,从而完成目标偏航后的快速修正。最后,针对某型作战无人机进行空战环境下的滚动优化导引以及视线角跟踪仿真,验证了所提方法对不确定性机动目标的拦截能力。
The modern air combat environment tends to be complicated,and it is difficult for traditional methods to obtain the ideal guidance effects for maneuvering targets.Therefore,an air combat guidance method based on top-level rolling optimization and bottom-level tracking is proposed for the modern unmanned aerial vehicle(UAV)air combat guidance problem.Among them,the top-level optimization based on the Gaussian pseudo-spectral method uses time as the performance index to quickly guide the UAV to the target area.When the target maneuvers,its trajectory is predicted and the guidance trajectory re-optimized.In addition,the underlying tracking method for the guide line of sight angle is introduced,so as to complete the rapid correction after the target yaw.Finally,the simulation of rolling optimal guidance and line of sight angle tracking in the air combat environment is carried out for a certain type of combat UAV,which verifies the interception ability of uncertain maneuvering targets of the proposed method.
