The invention discloses an array DOA estimation method for polarized signals, and the method comprises the following steps: 1, constructing covariance matrixes and cross-correlation matrixes of all poles pointing to an x axis and all poles pointing to a y axis on the basis of single-bit bipolar array sampling data, wherein the covariance matrix is represented as # imgabs0 # and # imgabs1 #, and the cross-correlation matrix is represented as # imgabs2 # and # imgabs3 #; 2, recovering the covariance matrix and the cross-correlation matrix by using a positive and negative chord rule to obtain # imgabs4 # and # imgabs5 #; 3, expanding the recovered covariance matrix and the recovered cross-correlation matrix into a vector form by using a differential array technology, and representing the vector form as xD, x, xD, y, xD, xy and xD and yx; 4, constructing the vectors in the step 3 to form a virtual signal receiving matrix XD, and constructing a spatial smoothing matrix according to the virtual signal receiving mat
