Abstract: In order to reduce response time of weapon systems and increase speed of information processing in mission planning system, a recursive route planning algorithm in the point of view of engineering application and on the idea of back reasoning from target position to warship position iteself was presented. Under some given condition, on the rule of the least number of navigation points which could complete the desired attack angle aviation, this algorithm can deduce next navigation point from target to the launcher in adverse direction of attack angle and get the planning route. Based on the planned route and in consideration of threats existed in the battle area, a tangetial route planning algorithm was proposed. According to the shortest planned route rule and the least number of adjusting planned routes, and by adding new navigation point or modifying old navigation point, this algorithm can adjust the planned old route to the shortest tangent of the threat area to avoid enemy. Simulation results show the validity and efectriveness of the proposed algorithms.
