摘要
提出了用信号带宽比特征识别雷达辐射源的新方法。通过两次对雷达辐射源信号进行平方处理,提取两次处理前后信号带宽的比值组成二维特征向量。利用四种常见的雷达辐射源信号进行的仿真实验结果表明,带宽比特征类内聚集性强,类间分离度大,能达到非常满意的正确识别率,证实了所提方法的有效性。
A novel approach which using the bandwidth ratio feature is proposed to recognize the radar emitter signal. A planar bandwidth ratio features vector is extracted by squaring the signal twice. Simulation result shows the bandwidth ratio features have small within-class distance and large between-class distance, and can achieve very satisfied accurate recognition rate through using four familiar radar signals. And the effectiveness of the proposed approach is confirmed
