Formation-flying guidance for cooperative radar deception

Radar range deception by generating a phantom target using cooperative electronic combat air vehicles is considered.Ageneralized kinematic framework for the required formation-flying is developed from the principles of line-of-sight guidance. Position, speed, and lateral acceleration expressions relating the phantom target and the vehicles are derived. The results are further analyzed for advanced missions of infinite time deception and minimum control effort deception. A control law for bringing the vehicles to a deceiving formation from any given initial arrangement is presented. The scenario of generating multiple phantom targets is discussed and analyzed for two or more radars. Simulations are carried out for homogeneous and heterogeneous groups of vehicles, showing the viability of the proposed methodology.
