APPARATUS AND METHOD FOR ESTIMATING LOCATION OF SINGLE SOURCE IN UNIFORM CIRCULAR ARRAY

摘要

PURPOSE: A location estimating apparatus of the single sound source signal and in the uniform circular array sensor and a method thereof are provided to estimate the location of the sound source with a small amount of calculation by calculating the 2-dimensional incidence angle of the incident sound source signal of the uniform circular array sensor and separately calculating the distance of the incident sound source signal. CONSTITUTION: The correlation between sensors that have symmetric relation to each other in the uniform circular array is estimated(S212). The conjugate correlation between the sensor having the symmetric relation is estimated(S214). An incident angle of the incident sound source signal is calculated using the correlation(S216). The incident angle and the distance of the incident sound source signal are calculated using the conjugate correlation(S218). The distance of the incident sound source signal is calculated by calculating the incident angle and the distance(S220). The location of the incident sound source signal is estimated(S222).
