    Compared with the traditional FFT,AR model has better frequency resolution and energy clustering for power spectrum estimation,thus it can be used to estimate the frequency.In this article,Marple algorithm of AR model is used to estimate the frequencies of a signal polluted by noises.The related factors of Marple algorithm to affect the estimation accuracy are discussed,and its effectiveness is experimentally simulated on a computer.The result shows that Marple algorithm is an effective tool for frequency estimation.
