other Embodiment approach

[0152] In other implementation manners, the anti-jamming strategy can also be: the action of adjusting the channel and bandwidth of the current communication signal by the unmanned aerial vehicle 11 for characterization learning, for example, the anti-jamming strategy g 1 Can be characterized as:

[0153] g 1 =g((B 1 →B 2 ),(a 1 →a 2 )), anti-jamming strategy g 1 Indicates that the learning drone 11 needs to set the current channel B 1 tune to channel B 2 , the current bandwidth a 1 Adjust to bandwidth a 2 ; In this case, the size of G is Y=B 2 × M 2 .

[0154] The initial Q value table can be an all-0 matrix with a size of X×Y, which can be specifically represented as:

Abstract

The invention provides an unmanned aerial vehicle communication Q value table determination method, and an unmanned aerial vehicle communication anti-interference method, a device and equipment. The Qvalue table determination method comprises the following steps: determining an interfered state set, an anti-interference strategy set and a reward function; determining an initial Q value table according to the interfered state set and the anti-interference strategy set; when the learning unmanned aerial vehicle is controlled to execute each anti-interference strategy, updating a Q value in theQ value table in a Q learning mode, wherein the updated Q value is associated with an anti-interference strategy adopted by the learning unmanned aerial vehicle, the power information and channel information of the received interference signal, and a reward function; the different interfered state information represents different power intervals and / or different channels where the power information of the interference signal received by the learning unmanned aerial vehicle is located, the influence of the external environment on the communication of the unmanned aerial vehicle can be reflectedmore comprehensively, and the determined anti-interference strategy better conforms to the actual flight condition.

Description

technical field [0001] The present invention relates to the field of unmanned aerial vehicles, and more specifically, relates to a method for determining a communication Q-value table of an unmanned aerial vehicle, an anti-jamming method, device and equipment for an unmanned aerial vehicle. Background technique [0002] With the continuous development of drone technology, more and more consumer drones are used in the daily life of ordinary people. [0003] During the flight of the UAV, malicious interference poses a great threat to the security of UAV communication. In order to deal with the threat of malicious interference, in the existing related technologies, when the communication of the UAV is interfered, by sensing the channel of the interference signal, the The communication channel of the drone is switched to a channel different from that of the jamming signal, so that the jamming signal can be prevented from interfering with the drone communication. [0004] It can...
