The unmanned aerial vehicle detection and countermeasure integrated machine is a dedicated detection and countermeasure device for unknown frequency band "low slow small" unmanned aerial vehicle targets and unmanned aerial vehicle cluster targets. The device is equipped with full frequency range drone signal detection, drone recognition, and automatically forms interference signals of specific frequencies and styles based on the detection and recognition results, thereby blocking drone remote control and image transmission signals, forcing drones to return and make forced landings.
