Abstract:

The remote control link of unmanned aerial vehicle(UAV)is often cluttered by interference which results in performance degradation or losing lock. The UAV remote control link of cognitive multiple input multiple output (MIMO) is presented. And the time frequent space code domain into UAV intelligent anti-jamming system is set up with congnitive radio. Many diversity such as time diversity, frequent diversity, space diversity and code diversity techniques are contained. The theoretical analysis and system simulation shown that the frequent diversity and code diversity can restrain the common narrowband and broadband interference of UAV remote control link based on the cognitive radio. And also the natural interference is restrained by MIMO space time diversity effectively. So it shows practical application value on the performance improvement of UAV anti-jamming.
