drone detection and neutralization system

Ctrl+Sky is a multi-sensor counter-drone system that is able to detect, track and neutralize intrusive drones. It is exceptionally effective because it is based on proprietary, patented technology and multi-sensor approach: from software to hardware.

how it works?

Thanks to the multi-sensor approach, Ctrl+Sky enables efficient detection, identification and neutralization of drones, day and night, in all weather conditions. Ctrl+Sky offers a scalable system approach to ensure a complete “dome” of protection from unwanted drone invasion.

The combination of proprietary radar, acoustic array, vision cameras and RF sensor allows Ctrl+Sky to minimize false alarms and detect even small drones at distances up to 2000 meters and neutralize them using two schemes.

The FMCW radar sensor operates in the X band and uses MIMO technology to locate drones. Ctrl+Sky operates on advanced algorithms for processing radar signals as well as tracking and classifying detected objects. The system can effectively distinguish drones from other flying objects, such as birds and simultaneously detect and track multiple drones, including swarms of drones.

The acoustic sensor is based on a microphone array – spatially spaced sound sensors – which allow for the formation and sweep of a directional acoustic beam, thus localizing sound sources in space. In addition, extremely advanced self-learning classification algorithms identify drones and memorize them, so that the system grows with functionality.

 

Video cameras register recordings of detected drones, so it is possible to present hard evidence of an intruder in a protected area. Also, cameras are of PTZ type and are zoomed on a drone by radar tracker. 30x optical zoom enables observation of objects located at a distance of 700 meters. Thanks to the convolutional neural networks, the camera is able to distinguish drone from birds.

The RF sensor (radio signal) identifies the radio communication between the drone and the operator. The sensor also allows the system to neutralize most popular drones, by forcing a return to the operator or simply back to the starting point. Moreover, white listing is enabled to allow friendly drones to the scene.

 

In the system set of Ctrl+Sky there is also a proprietary multi-band jammer, used to neutralize drones by jamming their communication link and navigation. Multi-band operation covers all used radio control bands of the drones as well as GPS/Glonass/Galileo/Beidou navigation. Jammer is using omni-directional or sectorial or directive antennas, according to client’s needs.

All detection sensors and neutralization schemes are smoothly integrated in a friendly web-based Ctrl+Sky CyView software. It is dedicated, web-based application for monitoring, configuration and control the system. It works in real-time mode. It is possible to integrate Ctrl+Sky CyView with other / external systems using an open API.
