The invention provides a single-bit spatial spectrum estimation method based on a support vector machine and relates to the field of support vectors in spatial spectrum estimation field and artificial intelligence in array signal processing. Problems of complicated calculation and quite low precision in conditions of single-bit extreme quantization and super-large scale antenna arrays are solved. The single-bit spatial spectrum estimation in a large-scale antenna array is modeled into a classification problem in artificial intelligence and the spatial spectrum of wave signals is solved by use of the support vector machine method. Compared with the traditional algorithm, the provided estimation method is advantageous in that estimation precision of the spatial spectrum is improved; the structure of a receiving machine is simplified; and angles of multiple signal resources can be simultaneously estimated. The estimation method is used for estimation of the spatial spectrums.
