Binary Integration of OS-CFAR detection in a nonhomogeneous background

Binary integration which can greatly improve detection performance with a simpler and less expensive receiver implementation is commonly used in radar systems. In this paper, the detection performances of OS-CFAR with binary integration in homogeneous and nonhomogeneous backgrounds are evaluated. There is an optimum L for binary integration (L/M) in homogenous background, but it gives the worst false alarm rate at clutter edges. Therefore, there is a compromise between the optimum L and the ability to control the rise of the false alarm rate at clutter edges for actual applications.
