Constant false alarm rate (CFAR) is a desired property for target detection in unknown and nonstationary sea clutter. Analysis of the experimental data shows that gamma distribution is a promising model for sea clutter. A robust CFAR method is proposed for target detection in nonhomogeneous gamma-di...
