Abstract
Root-MUSIC algorithm is a method of DOA estimation based on polynomial rooting. It estimated based on the cost function instead of peak searching, which greatly reduces the computation compared with MUSIC algorithm. However, it came with some other errors. In this letter, we propose a new method based on the the first-order derivative of the cost function and analyze the mean and the MSE of the proposed method. Simulation results show that the improved method performs better than the existing Root-MUSIC method.
