Abstract:

The research status and the system model of cognitive electronic warfare are described at the beginning, and a possible cognitive model of reconnaissance system is presented. Then based on the cognitive model of reconnaissance system, a digital channel frequency measurement method based on cognitive technology is proposed. Theoretical deduction and simulation shows that the digital channel measurement method based on cognitive technology greatly improves the signal to noise ratio and the frequency measurement accuracy compared to the traditional digital channel measurement method. And the feasibility of electronic reconnaissance based on cognitive technology is proved.

Key words: cognitive electronic warfare, digital channel, cognitive radar reconnaissance
