摘　　要：在雷达辐射源识别中,一般采用隶属度来衡量知识参数和侦察参数的相似性,并以此进行识别,其难点在于隶属度函数的确定。针对这一难点,提出了一种新的脉间特征参数和脉内特征参数隶属度的计算方法,并提出了一种综合特征权值的计算方法,对雷达辐射源进行加权识别。仿真结果表明,这种方法的识别效果优于传统的识别方法。In radar emitter recognition, the similarity of knowledge parameters and reconnaissance parameters is measured by the degree of membership which usually used to identify the radar emitter. The difficulty of this method is how the membership function should be determined. To determine the degree of membership, the method calculating the degree of membership of interpulse and in-pulse characteristic parameters is proposed, and a new method of determining weight coefficient of comprehensive feature is also proposed, which can be used for radar emitter recognition. Simulation results show that this method has better recognition performance than the traditional methods.
