The invention belongs to the signal processing field and relates to a receiving signal covariance matrix rank minimization direction-of-arrival (DOA) estimation method based on a spatial smoothing method. The invention aims to solve the problems of low angle estimation poor accuracy and low resolution of a traditional direction-of-arrival (DOA) estimation method under a condition of coherent signals and non-uniform noises. According to the receiving spatial covariance matrix rank minimization direction-of-arrival (DOA) estimation method based on the spatial smoothing method of the invention, on the basis of the traditional spatial smoothing method, a receiving signal covariance matrix is pre-multiplied and post-multiplied by an exchange matrix separately, so that a spatial backward smoothing covariance matrix can be obtained; the covariance matrix is reconstructed to be a noiseless covariance matrix based on the low-rank feature of the smoothing matrix; and finally a traditional MUSIC(multiple signal classification) algorithm is adopted to achieve DOA estimation. Numerical simulations show that the algorithm provided by the invention can better suppress the influence of non-uniform noises and has high DOA estimation performance under a coherent condition compared with traditional MUSIC, MC-MUSIC and RTM algorithms.
