Anti-jamming is a research area focused on developing techniques and technologies to protect communication systems, sensors, and other electronic devices from intentional interference or jamming. Jamming refers to the deliberate attempt to disrupt or block communication signals, which can pose a serious threat to military, security, and civilian systems. Anti-jamming techniques may involve signal processing, encryption, frequency hopping, and other methods to ensure reliable and secure communications in the presence of jamming attacks. Researchers in this field work to improve the robustness and resilience of communication systems against various types of jamming threats.
