Launch planning method for defense guidance of airborne missile

The invention discloses a launch planning method for airborne missile defense guidance, which comprises the following steps: calculating a flight path of an incoming attack missile from the current time to the moment of hitting an aerial carrier according to the motion states of the current incoming attack missile and the aerial carrier; establishing an interception projectile group formation form with interception feasibility through reachable set analysis and a coverage strategy; the method comprises the following steps: acquiring interception missile group formation forms at different time nodes, calculating time/angle constraints in three-dimensional middle guidance formation flight, and determining the interception missile group formation forms and launching opportunities of each missile; and the interception bullets are launched to carry out middle guidance formation flight, all the interception bullets reach corresponding positions in the formation at the same time under the expected bullet group forma
