一种基于变权理论的空中目标威胁估计方法

针对在威胁估计中使用较普遍的多因素常权综合法出现的问题，提出了一种基于变权理论的空中目标威胁估计方法。首先研究了因素取值变化对威胁结论的影响效果，然后根据备因素的变化形态动态调整其对应权值。在保证状态变权函数构造合理的情况下，可以有效减少不舍理结果数目。实例分析表明，采用变权方法得到的结果比常权的合理。

Air threat assessment based on variable weight theory

To deal with the problem of invariable weight aggregate in threat assessment, a method of air threat assessment based on variable weight theory was introduced. The method researched the threat result from the variety of factors value, dynamically changing the weight value according to the factors configuration. When the state variable weight function was created rationally, the number of unreasonable result would decrease greatly. The following computing simulation shows the result from new method is more reasonable than that from traditional methods.
