Embodiment
[0027] An intelligent decision-making method for UAV prevention and control based on compound interception strategy, the overall block diagram is as follows figure 1 shown, including the following steps:
[0028] 1) Use the UAV spectrum detection system to detect the black flying UAV and obtain the positioning information of the UAV. The UAV spectrum detection system mainly passively intercepts and receives the UAV and the operator's transmission through the omnidirectional array antenna. Remote control and image transmission radio frequency signals, the array antenna adopts N (N≥2, 12 in a typical embodiment) identical broadband antennas, and each antenna is installed in a different direction to form an antenna array covering 30*N degrees; the actual When working, select two adjacent antennas, input the two sets of intercepted regional signals into the signal processor, and the signal processor processes the signals. If it is confirmed that the signal is sent by the drone, co...

The invention discloses an intelligent decision-making method for UAV prevention and control based on a composite interception strategy. The spectrum detection system calculates the positioning information of the speed and direction of the drone according to the signal; 2) transmits the positioning information of the drone or the user-defined scene to the machine logic control system, and the control system establishes the relationship between input and output through a mathematical model The control system calculates the output results according to the input information and transfer function, and decides the interception plan to intercept the black flying UAV; 3) According to the interception plan, the composite interception system combines the basic interception means to intercept and Prevention and control; 4) Feedback the interception information of drones to the machine reinforcement learning system, continuously optimize the mathematical algorithm model of the machine logic control system through the machine reinforcement learning system, and improve and perfect the decision-making of the machine logic control system.
Description
technical field [0001] The invention relates to the fields of UAV flight prevention and control and artificial intelligence, in particular to an intelligent decision-making method for UAV prevention and control based on a composite interception strategy. Background technique [0002] In recent years, the application of drones has been increasing rapidly, both in military and civilian fields. According to incomplete statistics, in 2017 alone, the total sales volume of UAVs in the global market has exceeded 800,000 sorties, of which UAVs used in the military field accounted for about 10% of the market, while the remaining 90% were used. put into civilian use. At present, the development trend of drones is smaller size, lower price, and wider civilian use, and drones have been widely used in industries such as express delivery, terrain exploration, pesticide spraying, and cable inspection. Great results have been achieved in terms of economic and social benefits. However, as...
