The weak signal data enhancement method disclosed by the invention is high in data acquisition precision and strong in anti-interference capability. The method is realized through the following technical scheme: in a data enhancement model, original signal data specifying specific characteristics through a variational self-encoding module to generate a preliminary enhancement signal; mapping the probability distribution density and codes of the original signal data to a hidden variable sample space, and calculating a mean value and a variance of hidden variable samples of the original signal data; the generative network performing random sampling from known obeying likelihood distribution data to obtain hidden variables, and calculating a preliminary enhancement signal obeying Gaussian distribution; the generative adversarial module adopting a generator to carry out increment generation on the preliminary enhancement signal to obtain an optimal generator and a discriminator, the generator generating final enh
