摘要
Two new detectors are described to detect a broadband plane wave in a colored noise field using a line array. The signal spectrum and arrival angle as well as the noise field coloration are not known a priori. Using a two-dimensional mixed autoregressive model, a generalized likelihood ratio test and its weak-signal equivalent, the Rao test, are derived. The performances of the proposed detectors are shown by computer simulations to be superior to conventional Fourier-based methods. Finally, the detection results based on real data are presented.
