Abstract

The increasing demands for enhance information security in the national defense and military applications such as satellite communication and integrated RF front end, have led to a critical requirement for high-speed frequency-hopping systems. However, the traditional frequency-hopping systems which is based on electrical domain is limited by its own electronic bottleneck. For example, the bandwidth is generally limited to several GHz, and the speed is generally limited to ms. Therefore, this paper innovatively propose a frequency-hopping system which has wide hopping-frequency bandwidth and frequency-hopping speed by using microwave photonics. The system has a frequency hopping bandwidth of more than 70GHz, a hopping speed of up to ns, and a maximum support of 35 frequency points, which can greatly expand the application prospect of secure communication.
