Abstract: First, according to defects in search space and convergence time of traditional A* algorithm, an improved A* algorithm is put forward. Second, factors of comprehensive route planning in aircraft penetration phase are analyzed. On this basis, a cost function model is built up. Then radar suppression area under standoff jamming is researched on and the jamming location is ascertained. The comprehensive route planning model in aircraft penetration phase under standoff jamming is constructed. Finally, the path of aircraft penetration phase is planned comprehensively with improved A* algorithm. From the simulation, the improved A* algorithm can effectively work in path planning of aircraft penetration phase and decrease the cost of path, increase the probability of penetration to accomplish the mission.

Key words: A* algorithm, penetration phase, comprehensive route planning, standoff jamming
