| description | The invention discloses a geological radar migration and deconvolution digital identification method. The method comprises the steps of performing discrete wavelet transform decomposition on a radar wave image to obtain high-frequency coefficients and low-frequency coefficients of multiple scales; performing threshold processing and image reconstruction on the high-frequency coefficient and the low-frequency coefficient; a direct wave is obtained by adopting an average method, and a two-way wavelet amplitude spectrum is estimated based on the direct wave and a radar wave attenuation function; and calculating a deconvolution operator based on the two-way wavelet amplitude spectrum, and identifying abnormal waves by adopting an Euler deconvolution method. Through offset processing and deconvolution identification, interference of the environment and multiple waves can be effectively suppressed, and the accuracy of abnormal wave identification is improved.
