摘要
为提高巡航导弹的实时地形匹配概率,通过利用分形学中的分数布朗运动函数推导了地形分数维D和方差δ值的求解公式,提出利用分数维地形分析方法进行巡航导弹航迹规划的选取流程。依据该推导公式计算了地形图中地形区域的分数维和方差值,从而成功地比较了地形匹配的概率。实例表明,该方法能明显地增大地形匹配的成功概率。
Aim Terrain analysis is one important procedure in route planning for Cms. The main aim of it is to promote the real terrain matching probability, in this way, the targets can be destroyed successfully. By using the methods with FBM function, the formulas of finding the fractal dimension value and the variance are deduced. Especially a flow chart of the terrain analysis based on fractal dimension is proposed. Based on the deduced formulas the two character values are calculated and the corresponding matching probabilities are compared. Examples show that the constraint of fractal dimension in route planning can obviously increase the successful terrain matching probability.
