| Summary: | 碩士 === 國立清華大學 === 資訊工程學系 === 93 === The goal of source localization is to estimate the direction angle of source by means of Time Difference of Arrival (TDOA). In this research, we focus on how to estimate TDOA and implement four mentioned time domain methodologies, AMDF, ratioAMDF, Least Squares, and Cross Correlation.
Our experiment results demonstrate that almost all of the accuracy rates estimated by the four TDOA methodologies are about eighty percent. Furthermore, the costs of these methodologies are low. Therefore, these methodologies are not only able to be carried out on microcontrollers but also credible.
