Abstract
In this paper, we analyze the performance of the MOSCA-CFAR (Mean of OS and CA-CFAR), the SOSCA-CFAR (Smallest of OS and CA-CFAR) and the OSCAGO-CFAR (OS and CA-CFAR Greatest Of) detectors in homogeneous and non-homogeneous environments. The non-homogeneity is modelled by the presence of interfering targets in the reference window. In the presence of interfering targets in both windows the performances of these detectors degrade seriously. To overcome this problem we propose the GSOSCA-CFAR (Generalized Smallest of OS and CA-CFAR). Compared to the OS-CFAR, this detector performs better especially when the number of interfering is high.
