Abstract:

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.
