GLRT is an efficient method to resolve the detection issue of range spread targets in compound Gaussian clutter. But normal GLRT will be out of action when the velocity of target is unknown. Farther research is performed under this situation. An estimation algorithm of Doppler frequency based on general eigenvalue decomposition is proposed, which can estimate Doppler frequency effectively. And a Robust GLRT (R-GLRT) detector is designed. The results of simulation show the effectiveness of this detector.
