Principles of Anti-Drone Defense

The large increase in the number of drones, as well as the possibility of their use for malicious (illegal) purposes, has raised the importance of defense from them. This paper gives an overview of drones, the use of different modulation techniques, remote control systems and antennas since the knowledge and proper understanding of their characteristics enables the optimal choice of adequate protection methods. The paper also analyzes different aspects of modern and commonly used principles of anti-drone defense. Proper consideration of technical characteristics in the sphere of drone communication enables the focus on adequate solutions, depending on the specific protection requirements. Cognitive technologies have a significant place in terms of improving drone detection.
