A Research on 3D Fusion Location Algorithm of Spatial-time Domain Based on MUSIC Algorithm

In this paper, the new 3D fusion localization algorithm model based on the multiple signal classification (MUSIC) algorithm is proposed to integrate space distance positioning with time delay positioning. Space-time cascade approach enhances the receiver to receive signal strength in the range of signal source direction and the multidimensional spectrum peak search only needed in corresponding scope. Space-time fusion approach can match the airspace-domain parameters with time-domain parameters to estimate and handle the estimation problem in which source number is greater than the number of array element. The simulation results show that the accuracy of the signal source is estimated by using the 3D fusion location algorithm model when the pitching angle is less than 70 degrees.
