Abstract:In order to solve the problems such as unbalanced,strong interference and simultaneous existence of multiple frequency-hopping signals in frequency-hopping samples of UAV,an improved frequency-hopping signal detection algorithm based on deep residual network is proposed.The algorithm uses image Mosaic for data enhancement,attention module to improve robustness and accuracy, and adjustment of loss function to alleviate the problem of uneven positive and negative samples in data set.The experimental results show that the absolute matching rate of the algorithm on the multi-UAV signal data reaches 96.46% and the single class classification accuracy is no less than 96.92% :
