The allowable guidance handover area of Air-to-Air Missile (AAM) under the cooperative guidance of AWACS is studied.On the basis of analyzing the process of cooperative guidance,the mechanical models and motion models of the AWACS,the launching vehicle and the missile are set up respectively,and the restrictive factors that affect the handover area are analyzed from the aspects of the AWACS,the launching vehicle and the missile and their interrelationship.In the process of calculating the cooperative guidance handover area,the golden section method is used to simulate the model.In the simulation,different parameters of the AWACS and the missile are set respectively.According to the simulation result,the influence of these parameters on the guidance handover area is analyzed.The results show that,under certain situation,the guidance handover area has a positive correlation with the communication distance,the guidance distance,the beam width of the guidance antenna,and the beam width of the missile receiving antenna.However,the influence becomes less when the beam widths of the guidance antenna and the missile receiving antenna exceed a certain value.
