Embodiment

[0190] First, the detection range is delineated for the detection of the drone. Through the GPS positioning device equipped for each drone, each drone can obtain the coordinates of the current moment in real time. When the coordinates exceed the detection range at a certain moment, The learning behavior of the drone is adjusted by an algorithm, so that the drone avoids going out of bounds.

[0191] Then use the Markov model to define the collaborative process between multiple UAVs. Set the detectable range of the UAV as 2000m×2000m, the number M of UAVs as 10, the target to be detected as 100, the maximum time step T from the start of detection to the end of detection is 200, and each step lasts for The time is 5 minutes. In addition, it is necessary to set the longest distance and maximum angle for each UAV to fly within a time step. Here, the longest distance l is set to 20m, and the maximum angle θ is 360 degrees. Then each UAV first obtains environmental information, inc...

Abstract

The invention provides a radar communication integrated unmanned aerial vehicle cooperative multi-target detection method, and the method comprises the steps: carrying out the cooperative detection through employing a plurality of unmanned aerial vehicles to carry out the radar communication integrated equipment, setting each unmanned aerial vehicle as an intelligent agent, and training a stable detection strategy, and a trained strategy is used to control flight tracks of a plurality of unmanned aerial vehicles and resource allocation between the radar and communication, and finally a given detection task is rapidly completed. Radar, communication and unmanned aerial vehicle flight states observed by each agent are used as input of the strategy generation module, the state and action observed by each agent are mapped into a random strategy by using a deep neural network, and the strategy of each agent is evaluated by using the strategy evaluation module. And a better cooperation strategy is obtained through module training. According to the invention, through efficient planning of resources of radars, communication and the like on multiple unmanned aerial vehicles, multiple targets in a designated area are searched, and the multi-target searching and finding efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the field of radar communication integration and cluster cooperative detection, and in particular relates to an unmanned aerial vehicle cooperative multi-target detection method integrated with radar communication. Background technique [0002] / The same detection work only considers the resource allocation in the static environment, and no work considers the trajectory design of the UAV, and the trajectory design of the UAV is an important step to exert maneuverability and flexibility. For example, Fei Zesong, Liu Peng and Wang Xinyi designed a power control-based static radar communication integration UAV network utility optimization method; Chen Peng, Wang Min and Yang Zihan invented a UAV cluster static radar communication integration under reinforcement learning method of resource allocation. 3) UAVs often need time-varying channels and limited observation information when allocating radar communication resources in a dy...
