This paper studies PM algorithm in direction of arrival(DOA) estimation of signals, explains the principle of this algorithm, conducts simulation for uniform linear array with Matlab, concludes that PM algorithm has different performances in estimating DOA with different degrees between angles, different SNRs and different snapshots. With the comparison of PM with Capon, Music and Esprit algorithms, the advantages and disadvantages of PM algorithm are examined. The PM algorithm has fast calculation speed and small amount of calculation. In the scenarios of high SNRs, PM algorithm has high estimation precision and stability.
