The power global security solution establishes a reliable three-dimensional prevention and control system for the power industry, which can detect land and air intrusion targets (such as people, vehicles, drones, etc.). The scheme consists of a radar intelligent fusion perimeter warning system and a low-altitude defense anti-drone system. The perimeter warning system completes the accurate analysis of multi-dimensional information through the organic integration of millimeter wave radar and video processing technology at the signal level, and realizes high-precision real-time detection of perimeter intrusion behavior. The anti-drone system can detect and display intrusion targets in real time, monitor and analyze, locate and alarm, and deceive and drive away, providing a solid airspace protection layer for the power industry.
