Application of the utility model

A drone protection system is a complex complex of many subsystems that has the following mode of action.

The radar subsystem 7 performs continuous monitoring of the airspace protected by the system and registers all air objects in it. After analyzing the characteristics of the reflected signal from the air objects received by the radar antenna 21, the first computer 6 for controlling the radar subsystem 7 decides which of them are natural objects (eg birds) and which are mechanical objects (e.g. drones). The first computer 6 determines their coordinates and transmits them to the main computer 14, which displays them on the screen 13, marked with different symbols depending on the type of object. The host computer 14 performs the overall control of the drone protection system through specialized software. When an intruder drone 29 is detected by the first computer 6, the alarm subsystem 15 is activated, which triggers the audible siren 16.

In front of the main computer stands a system operator 28, which can request clarification of the nature of any of the air objects by marking the main screen 13. Thus marked air object becomes a target for verification by the optical subsystem. By a command given by the main computer 14, the third computer 9 of the optical subsystem gives a corresponding command to the infrared camera 11 or the high-sensitivity television camera 12 to aim at the target with a suitable magnification, which depends on the distance to the object. The third computer 9 of the optical subsystem has software that automatically decides to select the corresponding camera 11 or 12 depending on the level of ambient light at the moment. The resulting image is displayed on the third screen 8 of the optical subsystem and the operator 28 visually determines the nature of the target. If the target is an intruder drone 29, it marks it on the third screen 8 of the third computer 9. The software of the third computer 9 transmits a message to the host computer 14, which takes action to protect against this intruder drone 29.

The host computer 14 sends a command to the second computer 18 of the attenuation subsystem 19, which directs the attenuation antenna 20 to the target and starts attenuating its frequencies. The frequencies that are most widely used to control drones sold on the market and the frequencies are attenuated. of satellite navigation systems. In the general case of jamming the frequency of the intruder drone 29, it remains without control and orientation in space and must land

2896 Descriptions to utility registration certificates № 10.1 / 15.10.2019 or to "hang" fixed. If the jamming of the jamming antenna 20 does not block the intruder drone 29, the operator 28 sends a command via the host computer 14 to the first control unit 3 of the launch pad 4 and a protective drone 1 takes off from it.

The main computer 14 periodically receives data about the current coordinates of the intruder drone 29 from the first computer 6 for control of the radar subsystem 7 and transmits them to the second computer 18 of the attenuation subsystem 19, to the third computer 9 of the optical subsystem and to the fourth computer 23 of the subsystem. control of the protection drone 1. The fourth computer 23 directs the protection drone 1 to the intruder drone 29 through the radio antenna 25 of the terrestrial communication radio subsystem 24, thus the protection drone 1 is automatically directed to the intruder drone 29. When the protection drone 1 approaches the target, the intruder drone 29 falls in the field of view of the camera 30 located on the nose of the protective drone 1. The image of it appears in real time on the fourth screen 22 of the control drone control subsystem 1 and the operator 28 monitors the process of final convergence and collision between the two drones 1, 29. If necessary, the operator 28 can intervene through the control point of the fourth computer 23 of the control subsystem of the protective drone 1 and sending a signal via the radio antenna 25 to the receiver 33 of the protective drone 1 to correct its deviation, if any, by maneuvering through the steering mechanisms 36 and through the power modules 33 for electronic control of protective drone 1. The protective drone is equipped with a battery 32 to provide sufficient power for the duration of its flight. The final result of the flight of the protective drone 1 and its status are transmitted by the radio transmitter 31 for video and telemetry data, which transmits to the terrestrial communication radio subsystem 24 the data from the flight of the protective drone 1. The protective drone 1 moves on a trajectory 26 which changes so as to intersect the trajectory 2Ί of the intruder drone 29 as the two trajectories 26, 27 must intersect at the point of collision 2 in order for the final result of the flight of the protective drone 1 to be successful. the protective drone 1 is a failed collision, the software of the main computer 14 repeats the attempt to chase and collide with the intruder drone 29, firing another protective drone 1 from the launch pad 4, with or without the intervention of the operator 28. In a collision between the two drones 1,29 , they destroy each other. With this, the intruder drone 29 is prevented from fulfilling its mission.
