Portable drone countermeasure device

The target is independently and passively identified through the propagation of electromagnetic waves. By monitoring the remote control and video transmission signals of drones and comparing the received signals with a built-in template library, the type of drone is determined, providing reliable early warning of drone threats. The handheld countermeasure device generates electronic jamming signals to suppress the drone's radio control link/satellite navigation link, either driving the drone away or forcing it to land. The device is compact, lightweight, and ergonomically designed for easy portability and simple operation. It features long battery life and high reliability. Suitable for security at major events, counterterrorism operations, and border patrols, it serves as a mobile supplement to ground personnel systems after deploying fixed detection and countermeasure systems at high points, enabling dynamic gap-filling and real-time countermeasures.
