%X Path Planning methods based on known threats for an unmanned helicopter were proposed, an initial shortest path of an unmanned helicopter was developed by Dijkstra Algorithm. The path was re-planning when minatory districts were divided through threat weighting, and the path was smoothed under the conditions of maneuverability characteristics of an unmanned helicopter. If there was a pop-up threat, the path will be re-planning locally, so as to get the best path. And the correctness of the algorithm proposed was proved by the simulation in Matlab 6.5.
