Abstract The paper proposes a cooperative guidance law with constraints on guidance time and attack angle in twodimension plane, which can improve the penetration ability and combat effectiveness of multi-missile systems and adapt to the complex and changeable future warfare. By applying the second-order sliding mode control theory and using the backstepping method to ensure the stability of the system, through setting the trajectory of the expected attack angle, the cooperative guidance law with multiple constraints is derived. The guidance law is simulated under the condition that the target is stationary or moving. The guidance law can complete the cooperative guidance task with time and angle constraints within a certain limit range of lateral acceleration.
