Clutter suppression method, device and equipment for dual SVD (singular value decomposition) reconstruction strong motion and storage medium

The invention discloses a clutter suppression method, a clutter suppression device and clutter suppression equipment for dual SVD (Singular Value Decomposition) reconstructed strong motion, and a storage medium. The method comprises the following steps: constructing a Hankel matrix according to an echo signal received by a radar, and performing singular value decomposition and fast Fourier transform to obtain each singular vector frequency spectrum; judging the spectrum correlation coefficient of each singular vector spectrum and the first singular vector spectrum, and judging the spectrum waveform entropy of the singular vector with the high spectrum correlation coefficient value; constructing a Hankel matrix for a singular vector with a large frequency spectrum waveform entropy value, and performing singular value decomposition and fast Fourier transform; obtaining a new singular vector by reconstructing the Hankel matrix and the first inverse Hankel matrix; reconstructing a Hankel matrix according to the n
