| 摘 要： | 为提高雷达辐射源的正确识别率以满足航空电子对抗需求,提出基于非线性器件特征的辐射源识别方法.在非线性失真分析的基础上,通过谱再生现象的观测,对非线性器件的功率级数系数进行了估计,由于不同的雷达系统设计和随机组装,因此这种特征对每一辐射源是唯一的.仿真结果表明,该特征提取方法在低信噪比环境下可以获得高的辐射源识别率,证实...

| Abstract: | To enhance accurate identification rate of radar emitter to meet the requirements of modern information warfare,a novel method of radar emitter identification based on nonlinear device features is presented.Based on nonlinear distortion analysis,emitter signal spectral regrowth is observed,power series coefficient is estimated,and emitter feature is extracted.This feature is unique due to different system designs and fabrication randomness.Experiment results show that the method can achieve high accurate identification rate in lower SNR circumstance,which confirms the validity of the feature extracted approach. |
