A Design of Cognitive Anti-jamming System in Complex Environment

In complex electromagnetic fields, lots of electronic information equipments are working simultaneously, and these electronic equipments such as radar systems, communication devices, and jammers will interfere each other, and also create radio frequency interefence(RFI). The non-stationary RFI spectrum will usually produce damage to communication devices and radar systems over time. This research presents a design of cognitive anti-jamming system for identifying the potential threat and taking anti-jamming countermeasure. In order to relieve the effects of the RFI, the cognitive anti-jamming system is designed to have the ability to sense and adapt the threatening signal. These works in this research will provide reference for the development of cognitive radar or cognitive radio.
