| 摘 要： | 射频指纹的唯一性是基于射频指纹识别无线发射机的基础问题. 将元件制造容差与漂移容差统一为元件容差，将发射机的所有元件等效为一个元件，建立了等效元件的射频指纹识别系统的数学模型，并指出元件制造容差、元件漂移容差、ADC精度是射频指纹唯一性的主要影响因素. 对容差因素进行实验验证的结果显示，射频指纹具有潜在的唯一性.

| Abstract: | Uniqueness of radio frequency fingerprint is the foundation of transmitter recognition based on RF fingerprint. Mathematical model of RF fingerprint recognition system is constructed based on equivalent components having the same effect with overall transmitter components with manufacturing tolerance and drift tolerance. It is shown based on the model that component manufacturing tolerance, drift tolerance and ADC precision are principal influence factors of uniqueness of RF fingerprint. The tolerance-factor is validated in experiments. The results indicate that RF fingerprint is potentially unique. |
