The present invention discloses a locating and tracking method based on a sound source array, comprising the following steps: S1, acquiring on-site sound through a quintuple microphone array, and pre-processing a sound signal acquired by each microphone in the quintuple microphone array to obtain an audio signal; S2, performing sound source locating for the audio signals according to arrival time delay of the audio signals between the microphones and positional information of the microphone array, so as to calculate a pitch angle, an azimuth angle and an object distance; and S3, moving and turning a locating and tracking apparatus to arrive to a sound source position. The locating and tracking method of the present invention performs related processing for influences of non-gauss noises, coherent noises and indoor reverberation of the sound source on accurate locating, thereby improving accuracy of locating of the sound source.
