A novel method based on orthogonal redundancy sampling is proposed for har-monies estimation, which utilizes orthogonal redundancy sampling to obtain a signal with the information of its frequency range, and decomposes signal s auto-correlation matrix into the summation of rank-1 matrixes to estimate frequency of harmonics with the information. The results are compared with that of MUSIC and AR algorithms, and find that this method has a lower SNR threshold and higher range resolution.
