摘要

Dear editor, Target detection is a basic function for any radar system [1].For the problem of generalized direction detection,two adaptive detectors were proposed in [2],according to the generalized likelihood ratio test (GLRT).For the above problem,under the signal-presence hypothesis,the rows and columns of a rank-one matrix-valued signal belong to known subspaces;however,the corresponding coordinates are unknown.The resulting detectors share the form of maximum eigenvalues of proper matrix productions,composed of test data and training data.As an eigenvalue corresponds to an eigenvector,which in turn serves as a direction,these detectors work in a manner wherein they try finding a direction with the highest possibility.Hence,they are usually called direction detectors or generalized direction detectors.
