In this paper, a TD-MUSIC spectrum estimation model based on directional antenna is proposed. The model contains three directional antenna arrays with uniform line, by which the TD-MUSIC spectrum peak was calculated and analyzed. The linear relationship between the amplitude of the signal source and the pitch angle was calculated by inverse trigonometric function. The simulation results show that the pitch angle estimation of the signal source can be obtained by the improved 3D localization algorithm model fast and accurate.
