AI Technical Summary

Technical Problem

Existing technologies are insufficient to effectively cope with frequency hopping communication systems under agile interference modes, leading to a decline or interruption in communication performance. Traditional, frequency adaptive, and power adaptive frequency hopping systems cannot effectively avoid interference when the interference pattern changes rapidly.

Method used

By acquiring the patterns and occurrence probabilities of agile interference through spectrum monitoring, calculating the occurrence frequency of each frequency hopping point, and constructing a pseudo-random frequency hopping sequence, the anti-agile interference capability of the frequency hopping communication system can be improved.

Benefits of technology

In the agile jamming mode, the information transmission accuracy of the frequency hopping communication system is improved, and the ability to resist agile jamming is enhanced.
