摘　　要：对于未知雷达信号的判别和归类一直是雷达对抗侦察情报处理中的一个难题。提出了一种新的基于距离测度区间灰关联决策的判别方法。该方法采用距离测度区间来衡量两个雷达脉冲序列之间的相似性,并利用灰关联分析的方法进行相似性比较和决策,最终完成对未知雷达信号的判别和归类。仿真结果表明,在模板脉冲序列受噪声污染较小时,该方法识别准确率较高。It is a difficult problem to identify and classify unknown radar signals in information processing of radar countermeasures. A new identification method based on distance measure interval gray correlation decision technique is proposed here, in which the differences between two pulse sequences are measured by distance measure interval and through comparing the distance measure interval based on gray correlation decision technique the unknown pulse sequences can be identified and classified. The simulation results show that a high identification accuracy rate can be obtained when the existing template sequences are polluted slightly.
