Abstract: The present disclosure relates to a radio astronomy interference signal reduction method, apparatus, and system and a computer device. The method includes: acquiring at least two beam signals, and obtaining a covariance matrix between all the beam signals according to the beam signals, wherein the beam signals include subsignals from at least two directions; performing eigen-decomposition processing on the covariance matrix to obtain signal eigenvectors and eigenvalues corresponding to the subsignals, and extracting interference eigenvectors corresponding to interference signals from the signal eigenvectors based on the eigenvalues; and obtaining a target reduction result for the interference signals according to the signal eigenvectors and the interference eigenvectors. With the method, the problem of low accuracy of radio astronomy interference signal reduction in the related art can be solved.
