| Abstract: | Principles of two dimensional MUSIC algorithm has been introduced in this the. Two methods for searching the spectrum peaks are indicated, i.e., method in solving the inflexions of spectrum function and method with variable searching step. Simulations prove that the two methods can obvionsly improve the speed in searching direction finding with MUSIC algorithm. |
