Persymmetric adaptive target detection without training data in collocated MIMO radar

For adaptive target detection in a collocated Multiple-input multiple-output (MIMO) radar with a symmetrical spaced linear array, we propose an adaptive detector according to the generalized likelihood ratio test (GLRT) criterion. The proposed detector does not need training data and exploits the persymmetric structures in the receive signal. Simulation results show that the proposed detector significantly outperforms the conventional detectors when the number of the transmit waveform samples is moderate.
