A Frequency Hopping Network Station Sorting Algorithm Based on Improved YOLOv8
摘要
Abstract
Aiming at the problem that traditional frequency hopping network station sorting technology is ineffective under low signal-to-noise ratio conditions and has poor real-time detection performance,this paper proposes a shortwave frequency hop-ping signal sorting algorithm based on the improved YOLOv8(You Only Look Once version 8).First,the short-time Fourier transform is performed on the received aliasing signal to generate a grayscale time-frequency image as the input of the YOLOv8 network model.Secondly,in view of the impact of frequency collisions between aliasing signals such as sweep frequency signals,fixed frequency signals and frequency hopping signals on detection accuracy,the Deform-able Convolutional Net-works v2 is introduced in the C2f layer to improve the generalization ability of network feature ex-traction.Thirdly,the Simam attention mechanism is added to the backbone layer to solve the problem that background noise is easily confused with frequency hopping signals and affects detection accuracy under low signal-to-noise ratio.Finally,the convolutional kernel of Detect module is replaced by Partial Convolution kernel,which reduces the computational complex-ity of the network by 32.18%without the accuracy loss of mAP@0.5 exceeding 0.37%,and improve the inference speed of the network model.Experimental results show that the improved YOLOv8 algorithm proposed in this paper has a separation rate of 97.68%at-5 dB signal-to-noise ratio,and the model has fast convergence and strong robustness.关键词
