Abstract

We propose and demonstrate an anti-jamming system to defend against wideband jamming attack. Free space optical communication is deployed to provide a reference for jamming cancellation. The mixed signal is processed and separated with photonic signal processing method to achieve large bandwidth. As an analog signal processing method, the cancellation system introduces zero latency. The radio frequency signals are modulated on optical carriers to achieve wideband and unanimous frequency response. With wideband and zero latency, the system meets the key requirements of high speed and real-time communications in transportation systems.

摘要

我们提出并演示了一种抗干扰系统，以抵御宽带干扰攻击。采用自由空间光通信为干扰消除提供参考。利用光子信号处理方法对混合信号进行处理和分离，以实现大带宽。作为一种模拟信号处理方法，该消除系统引入了零延迟。射频信号在光载波上进行调制，以实现宽带和一致的频率响应。该系统具有宽带和零延迟的特点，满足了交通系统中高速实时通信的关键要求。
