【摘要】 对雷达辐射源识别中的权系数赋值问题进行了研究,提出了层次-粗集组合赋权法。该方法利用粗糙集理论的属性约简和属性重要度原理,删除了冗余属性,构造出客观判断矩阵,然后与层次分析法的主观判断矩阵相结合,得到组合判断矩阵,最后计算出权重,从而实现了主客观方法共同赋值。仿真表明,本方法所得权系数在进行雷达辐射源识别时有较好的结果。更多还原

【Abstract】 The assignment of the weighting coefficient in radar radiation source recognition is analyzed,and the hierarchy-rough set combined weight assigning method is presented.Based on the principles of the attribute reduction and significance in the theory of the rough set,the method removes the redundant attributes,creates the objective judgment matrix,which is combined with the subjective judgment matrix to obtain the combined judgment matrix,and finally calculates the weights to realize the common assignment of the subjective and objective methods.The simulation shows that the weighting coefficient obtained through the method is of better results in radar radiation source recognition.更多还原
