    Abstract
  • To resolve the problem of fast estimating two-dimensional direction of arrival (DOA) in coherent signals environment with two parallel linear arrays, a new method for single-snapshot two-dimensional DOA estimation was presented based on noncircular signals. New coordinate system was established and array received data was changed to its conjugate data. Pseudo snapshot data was made and array aperture was doubled by reconnecting data. The coherence between the signals was solved and two-dimensional DOA can be estimated only by using singular values decomposition (SVD) for extended matrix which was made of three pseudo snapshot matrix. The method has low complex degree and high estimation accuracy, so it is suitable for DOA estimation of high real-time attribution background. Simulation indicates that the method is effective.
