Abstract:With the rapid development of new technologies such as artificial intelligence, communication technology, and unmanned systems, the intelligence level of communication countermeasure equipment has been continuously improved, and the concept of unmanned swarm combat has also been continuously deepened and developed . All these have brought new opportunities and challenges to the research of cognitive electronic warfare techniques, and also promoted the development of cognitive electronic warfare from single intelligence to swarm intelligence. To ensure the development of cognitive electronic warfare being adapt to the new unmanned swarm combat style in the future, this paper first reviewed the concept and the connotation of cognitive electronic warfare and the research background of cognitive electronic warfare single intelligence as well, then prospectively put forward the concept of cognitive electronic warfare swarm intelligence and elaborates its connotation in detail, and finally pointed out its research value, application value and development prospect for cognitive electronic warfare. In the end, from the perspective of system confrontation, this paper further made a more comprehensive prospect of the possible future development direction of cognitive electronic warfare swarm intelligence.
