工作的估计

The advanced research work of this paper is: we realize two kinds of DOA estimation arithmetic on the MATLAB software environment. One arithmetic is traditional arithmetic, which include Time-delay method and Capon method. The other one is MUSIC arithmetic. Then we qualitatively compare the performance of these arithmetic with each other.
