This paper presents a cooperative control scheme for electronic attack of multiple Electronic Combat Air Vehicles (ECAVs). The stealthy ECAVs equipped with ECM can deceive the radar by using range delay deception technique. This makes the radar to detect a fake target called Phantom beyond the ECAV location. The important feature of generating phantom track is kinematic and dynamic constraints. These constraints restrict the freedom of Phantom tracks. This paper presents three-dimensional mathematical relationships between the motion of the ECAV and the motion of the phantom. Based on the mathematical model, the trajectory generation problem is formulated as an optimal
control problem. The control input parameterization converts the optimal control problem into the parameter optimization problem with inequality constraints. This problem is solved by using the sequential quadratic programming method. The numerical result for the optimal phantom trajectory generation is presented.
