In this paper, a novel two dimension (2-D) direction of arrival (DOA) estimation method based on complementary sequence and ESPRIT algorithm under parallel coprime Arrays is proposed for multiple input and multiple output (MIMO) system. Unlike the traditional method, the complementary sequence is used as the transmitted far-field signals. Due to the orthogonality of the complementary sequence, the DOA estimation performance can be improved. Based on the parallel coprime array, the novel ESPRIT algorithm can be used to acquire accurate DOA estimation by searching the coincide values from ambiguous estimation results. In addition, we give the experimental results and show that the proposed algorithms can obtain higher DOA estimation resolution and distinguish more targets.
