【摘要】 在应用数字仿真法研究导弹地形跟踪飞行的撞地概率时，首先要对导弹飞越的真实地形进行数值模拟．在充分探讨了地形模型和随机过程实现的基础上，采用波叠加法仿真了３ 种典型地形．研究了子波数对仿真结果的影响，说明选取一定数目的子波即可得到满意的结果．该工作对武器系统评估及撞地概率研究有重要应用价值．更多还原

【Abstract】 Terrain numerical simulation is the prerequisite problem in study of terrain following missile clobber probability by adopting digital simulation method. Three typical terrains are simulated using wave superpose method based on the work of full exploration of terrain model and its realization .Effect of wavelet number on simulation result is studied,the results indicate that satisfactory results can be obtained by selection of a certain wavelet number.This work is of great practical values to weapon system evaluation and clobber probability research.更多还原
