Abstract

As the electromagnetic environment becomes more and more complex and strong electromagnetic interference becomes normal, in order to improve the ability of ultra-wideband(UWB) communication under strong resistance and complex electromagnetic environment, the wideband communication anti-interference technology has been applied more and more widely in electronic information systems. Based on the advantages of microwave photonic technology such as ultra-wideband and anti-interference, this paper constructed an ultra-wideband adaptive anti-interference communication system by combining microwave photonic spectrum sensing and high-speed frequency hopping signal generation. In the ultra-wideband adaptive anti-jamming communication system, the spectrum sensing module carries out high-speed real-time sensing of electromagnetic environment, the intelligent processor decides the safe spectrum information according to the spectrum sensing information, and the frequency-hopping signal generation module generates high-speed frequency-hopping signals according to the decision information, which can realize the adaptive anti-jamming of ultra-wideband communication. In the simulation, the 2~18GHz frequency spectrum is perceived at a high speed by using a coherent optical comb, and a frequency hopping pattern is determined according to the perceived information. The frequency hopping signal generation module generates a frequency hopping signal of 20000 hops /s according to the frequency hopping pattern, which improves the adaptive recognition ability of the communication system in the UWB range.
