On-line Avoidance strategy with Multiple No-fly Zones

Abstract

A novel online avoidance strategy with multiple no-fly zones is proposed based on real-time selection and dynamic programming. The no-fly zones are classified and screened via relative position between flight path and the no-fly zones described by route offset distance, and the boundaries to flyover are determined by using the dynamic programming method. With the boundary points, the entire gliding flight process is divided into several series stages, and then the sub-guidance algorithm is employed to realize multiple constraints guidance. Finally, the simulation is carried out to show that this method can avoid more than one no-fly zone and provide a reference for further research on avoidance guidance in multi-no fly zone.
