摘　　要：在对反舰导弹低空突防中的火力威胁进行分析的基础上,将其划分为已知固定威胁、已知移动威胁和未知威胁三类,分别建立了这三类威胁的矢量模型。为了充分利用地形的遮蔽作用,针对已知固定威胁提出了一种基于矢量地形改进通视性算法的反舰导弹低空突防威胁处理方法,分析了算法的复杂度。通过仿真证明了所提出的威胁处理方法能够提高反舰导弹航路规划程序的性能,并得到更优化的解。Based on the analysis of threats in low altitude penetration of antiship missile, threats were sorted by three types as known fixed threats, known movable threats and unknown threats. The vector models of each type of threat were established. To utilize the shield of terrain, a processing method of known fixed threats based on an improved inter-visibility algorithm of vector terrain data was proposed, and its complexity was analyzed. It was proven by the simulation that route planning programs using the proposed method of threat processing would get a faster convergence rate, as well as a better result.
