Research on VMD of physical signs information based on improved GOOSE algorithm
This paper relies on the 60 GHz frequency modulation continuous wave(FMCW)millimeter wave radar,uses the improved GOOSE algorithm,combines tent chaos mapping in the population initialization stage,and uses the Levy flight strategy in the exploration stage to improve the global search capability of the algorithm.Then,the improved GOOSE algorithm is applied to variational mode decomposition(VMD)to obtain the optimal values of k and α.Improvements of the GOOSE algorithm improve the precision of respiratory heart rate detection.Finally,the experimental results show that the improved GOOSE optimization algorithm is used to adaptively optimize the parameters of the VMD algorithm.Through the post-reconstruction analysis of the signal,the noise component is effectively removed and the decomposition efficiency is improved.
