Abstract :
In this paper a simple and effective GLRT algorithm is proposed to detect distributed target embedded in unknown Gaussian noise, under unknown Doppler frequency. Target´s signature and velocity are accurately and simultaneously estimated during detection procedure without resorting to conventional algorithms like MUSIC, root MUSIC or ESPIRIT. Simulation results revealed high detection performance and target estimation under relative low SNR.
