摘要

近年来，无人机在非法活动中的使用有所增加。对付它们在限制区域行动的一种方法是在目标无人机使用的频率上发射高功率干扰信号。为了提高干扰器的性能，引入了全双工干扰器。在全双工系统中，收发器能够使用相同的时间-频率资源进行发送和接收，这允许设备进行频谱监测，同时通过传输干扰防止无人机操作。在本研究中，实验测量了典型干扰波形的自干扰消除，并对不完全自干扰消除的样本进行了信号检测。

Self-interference Cancelation Performance in Full-Duplex Jamming and Spectrum Monitoring

The use of drones in illegal activities has increased in recent years. One method for countering their operation in restricted areas is by transmitting a high-powered jamming signal over the frequencies used by the target drone. To improve the performance of jammers, full-duplex is introduced. In full-duplex systems, the transceiver is able to transmit and receive using the same time-frequency resources, which allows a device to conduct spectrum monitoring while preventing drone operations by transmitting jamming. In this study, the self-interference cancelation of typical jamming waveforms is experimentally measured and signal detection is performed over samples with imperfect self-interference cancelation.
