Military engineers first developed drones, and then they understood that the opponent might also have such tools, so it is good to have equipment that will allow them to defend themselves. Three British companies are working on the Auds program, which is intended to be a very effective weapon against unmanned vehicles.
Auds (Anti-UAV Defense System) is a defense system designed specifically to combat drones, which can pose a great danger to soldiers and their equipment. It is not a weapon based on missiles or rockets, but on communication distortion. The system is equipped with powerful transmitters that disrupt communication between the dron and the control panel and thus deprive the operator of the machine control.
Auds detects unmanned vehicles with a built-in camera with the ability to record a thermal trace, and then sends a strong signal to them in order to disrupt the signal.
