Kaspersky Lab company introduced a system that allows you to protect the territory from the passage of drones. It detects the drone using cameras, radar, lidar or microphones, recognizes the model of the drone and sends radio interference in its direction, because of which the device loses contact with the operator and makes a landing.

The decline in the cost of civil multicopter in recent years has led to a sharp increase in their prevalence. This led to both positive results (for example, made aerial photography more accessible) and negative (for example, blocking airports). To protect against drones, engineers develop various means of control, working on different principles. One of the most common methods is jamming. This allows you to interrupt the communication between the drone and the operator, and also does not destroy the device, because after blocking the signal, it either returns to the takeoff place or lands safely at the point of disconnection (this is standard behavior for commercially available drones).

The system can simultaneously monitor various objects, but one neutralization station can interfere with the operation of only one drone or several that are not far from each other, since the antennas in it create a narrowly focused signal. The order of work with objects is determined by the probability that the detected object is a drone. In a future version of the system, developers are going to add the ability to choose the priority of goals by the operator.
The prototype that the company showed at the presentation consists of a rack with a radar and lidar, another rack with several cameras, a jamming and tracking station, and a computing module. In the current hardware configuration, the system is able to control airspace within a radius of about a kilometer, but engineers note that the distance can be higher if, for example, a camera with a large focal length and resolution is used.

The developers note that the cost of the demonstrated minimum set is about one hundred thousand dollars, however, the price can be higher and depends primarily on what equipment the customer chooses. The company can also integrate its software at facilities that are already equipped with suitable surveillance cameras and other equipment.
