Aiming at improving the survivability of unmanned aerial vehicle (UAV) in radar threat situation, a method of UAV route planning based on analytic hierarchy process (AHP) is proposed. Compared with the previous model of the route planning, a variety of qualitative factors and quantitative factors, such as the spatial positions of both UAV and radar and the detection probability of the radar, are introduced for providing a more accurate description of radar threat and the jamming effectiveness of UAV. Then the ant colony algorithm is applied to the route planning problem based on the dynamic ECM model. Simulation results show that the proposed model is efficient in solving the route planning problem of UAV.
