A new penetration route planning method based on the dynamic aircraft RCS model

The survivability of aircraft can be enhanced by appropriate penetration route planning method. The existing model of the operation space for route planning can not reflect exactly all characteristics of the radar threat environment. This paper proposed a new method for radar modeling by introducing the artificial potential field (APF) approach for robot route planning. In view of the variation of the radar threat environment according to the different observed radar cross sections (RCS) during each time interval, the dynamic aircraft RCS model was proposed, and the dynamic APF model of radar threat for route planning was built on this RCS model. Additionally, a RCS data process program is applied to satisfy the real-time requirement of route planning. The simulation results indicated that this new kind of model can reflect the variation of radar threat environment during the penetration phase and the obtained penetration route is more rational.
