| 摘 要： | 射频(RF)功率放大器是辐射源射频指纹特征产生的关键器件之一，是射频指纹(RFF)产生机理和个体识别的重要突破口。设计一种功率放大器射频指纹提取实验方法，利用时域射频独特原生属性(RF-DNA)方法成功提取了功率放大器的射频指纹，并对RF-DNA指纹进行了可视化处理。研究结果表明，功率放大器的射频指纹主要反映在幅度失真特性上，利用瞬时幅度生成的时域RF-DNA指纹能够实现对放大器个体的分类，在信噪比大于12 dB时，分类正确率在91%以上。可视化后，能直观观察RF-DNA指纹及不同功率放大器之间统计特征的相似性和差异性。

| Abstract: | Radio Frequency(RF) power amplifier is one of the key components that generate the Radio Frequency Fingerprint(RFF) of transmitter. The research on RF amplifier is a key breakthrough for RFF generation mechanism and individual identification. For this reason, an experimental method for RFF extraction of power amplifier is designed, which is called time domain RF Distinct Native Attribute(RF-DNA). The method successfully extracts the RF fingerprint of the power amplifier and the time domain RF-DNA fingerprint is visualized. The research results show that the RF fingerprint of the power amplifier is mainly reflected in the amplitude distortion characteristics. The time domain RF-DNA fingerprint generated by the instantaneous amplitude can achieve the correct classification of the amplifier individually. When the SNR is higher than 12 dB, the classification correct rate is above 91%. The visualized RF-DNA fingerprint can be intuitively observed, as well as the similarity and difference of statistical features among different power amplifiers. |
