Phantom track generation using predictive control concept

A guidance law which generates a coherent phantom track to deceive a radar network through a team of unmanned aerial vehicles (UAVs) is addressed. If all UAVs are located along the line of sight from their corresponding radars to the phantom then radars detect an erroneous target called a phantom beyond the location of the UAVs by using the range delay deception technique. The problem is viewed as a line of sight (LOS) guidance problem and a guidance law based on predictive controller is developed in order to make the UAVs track LOS of the phantom. Additional states which makes the parallel motion of UAV and phantom is added to predictive controller structure. A closed form solution is obtained for control inputs of UAVs corresponding to given phantom track. Simulation results are given validating the performance of proposed method.
