战场态势分析是指挥决策的基础，D-S证据理论广泛应用于不确定性下的近似推理，尤其在战场的态势估计中起到了重要作用。为了降低命题中含复合焦元时的不确定度，需要运用概率转换方法如Pignistic方法等对这些焦元进行概率转换。当存在命题的基本信度赋值函数（ BBA）bba（全称）为零的情况时，一些常规的概率转换方法不能处理，即使能处理这种情况的概率转换方法在降低不确定度方面也没有达到理想效果。提出利用HDSmP方法将信度函数近似转换成概率函数，不仅可解决辨识框架中存在信度为零的命题时的情况，而且可以降低不确定性。此外，对HDSmP方法中比率再分配因子的取值进行了分析，通过实例验证了该方法在战场态势估计中的可行性和实用性。

The battlefield situation assessment is the basis for decision-making,Dempster-Shafer evidence theory is widely used for approximate reasoning under uncertainty,and it plays an important role especially in the battlefield situation assessment. In order to reduce the uncertainty of compound focal elements of propositions,probability transformation methods such as Pignistic methods are adopted to transform these focal elements into single focal elements with reduced uncertainty. When there is a proposition whose Basic Belief Assignment (BBA)bba equals to zero,it is impossible for some conventional probability conversion method to solve the problem. And even if it can be addressed through some probability conversion methods,it’s not ideat in reducing the uncertainty after the transformation. In this paper,the usage of HDSmP transformation method is put forward to approximate a belief function into a probability measure,which not only solve the situation where there are propositions whose belief values equal to zero in the discernment framework,but it also reduce uncertainty of the proposition. In addition,the analysis of the proportional redistribution factor(ratio) in HDSmP method is presented. Finally,the feasibility and practicability of the method are illustrated through examples of the battlefield situation.
