摘要
针对雷达告警系统中对未知辐射源信号告警不准确的问题,利用集对分析和粗集理论构造一个综合性评价模型,通过选择未知辐射源信号的多个属性指标,同时给出各属性指标的隶属度函数,然后在用熵值法确定各属性指标权重值的基础上,实现对未知辐射源信号的威胁等级排序。最后通过实例验证了该方法能对雷达数据库中未搜集的未知辐射源信号的威胁等级进行有效判定。
In order to solve the problem that the radar warning system doesnt have high accuracy when the research target is unknown radiant point,a comprehensive model is proposed based on SPA（Set Pair Analysis）and rough-set theory.Several attribute indexes are selected,and their own membership function is given,then the menace grade of all indexes are ascertained with entropy value method.On the basis of this,the unknown radiant pointsmenace level are assessed.The example shows the practicability of the model.
