Space-time joint sound source localization method based on CNN and MUSIC

The invention discloses a space-time joint sound source localization method based on a CNN and MUSIC, and belongs to the technical field of sound source localization, and the method comprises the steps: receiving sound signal data through a sensor array, obtaining the observation data of a signal source, carrying out the spatial domain processing and time domain processing of the sound signal data through a neural network model CNN and MUSIC algorithm, and obtaining a localized coordinate position. According to the invention, a sound source position is solved by using a traditional spatial smoothing MUSIC algorithm twice, a hidden vector space is found by using automatic coding and decoding to carry out audio signal denoising, time domain information of a sound signal is extracted by using a convolutional neural network, and sound positioning is realized through spatial-temporal combination of CNN and MUSIC. The method can be used for target selection and interference suppression in communication equipment or
