Abstract This paper considers the guidance issue for attackers against aircraft with active defense in a two-on-two engagement, which includes an attacker, protector, defender and target. A cooperative line-of-sight scheme prescribed performance input saturation is proposed utilising sliding mode control theories, guarantees that attacker able to capture target assistance of protector remaining on between order intercept defender. fixed-time function first-order anti-saturation auxiliary variable are designed game strategy constrain overshoot satisfy requirement overload manoeuver. The alleviates influence external disturbance by implementing observer chattering phenomenon caused sign function. Finally, nonlinear numerical simulations verify strategies.
