Abstract : The robustness of a subspace generalized likelihood ratio test (GLRT) detector to signal mismatch is addressed for data conforming to the generalized multivariate analysis of variance model. This model assumes a deterministic signal of known form in the presence of unknown, colored, Gaussian noise. The subspace GLRT compresses data into a lower dimensional subspace prior to detection. It is shown in the paper that a subspace GLRT reduces the performance loss due to mismatch relative to that of a nonsubspace detector.
