摘　　要：战场态势评估是指挥决策的基础,如何进行合理的态势评估是C4ISR数据融合系统中的一个重要环节。针对态势评估中的证据在合成过程中的重要程度不同,通过引入证据权重值,提出了一种新的D-S证据理论合成方法。实验表明该方法可提高态势评估中证据合成的合理性与可靠性,能得到更理想的合成结果,更符合实际情形。The analysis of the battlefield situations is the basis of command decision, and situation assessment is one of the most important components in C^4ISR data fusion systems. Considering that the importance of different evidences is different in situation assessment, a new evidence combination method is presented by introducing evidence weight coefficient. In this improved method, the importance of the evidences is calculated. Experiments showed that this method can improve the rationality and reliability of evidence combination in situation assessment, and guarantee better result.
