A Hybrid Guidance Strategy for High-Speed Aircraft Facing Threat Zones

The increasing complexity of the adversarial environment has led to more complex threat situations for high-speed aircraft, such as radar detection and missile interception, posing great challenges to the guidance and control process of the aircraft. In response to the above issues, a guidance strategy is designed for high-speed aircraft facing threat zones, which first constructs a guidance strategy for threat areas, combining the detection advantages of the guidance head and the threat situation, and designs avoidance strategies for the aircraft in different situations. Guided by the avoidance strategy and combined with an improved proportional guidance method, the guidance trajectory of the aircraft under the threat boundary was established, and the normal overload required for the aircraft to effectively avoid was derived by an improved guidance method; On this basis, the required overload of the aircraft is taken as the control input, and a robust controller for the aircraft based on sliding mode control is designed. Combined with the simulation model, the guidance and control simulation analysis of the aircraft is carried out to verify the effectiveness of the proposed strategy.
