Low Observability Trajectory Planning for Stealth Aircraft Penetrates Netted Radars

To achieve low observability trajectory planning for stealth aircraft penetrates netted surveillance radars,the properties in penetrating process are analyzed firstly. And it establishes an information fusion model depending on the models of monostatic radar and bistatic radar system. Then the trajectory planning problem is described with a mathematical method into an optimal control problem of complex multi-objective nonlinear continuous time,which considers the stealth ability, warning time and the fuel consumption with various restrictions. After that,the meyhod based on pseudospectral method is put forward for the low observability trajectory planning problem. Simulation results achieves the low observability trajectory planning for stealth aircraft penetrates netted surveillance radars and demonstrate the feasibility and availability of the proposed method.
