Abstract:
For improving the detection performance of the radar constant false alarm rate(CFAR)in the nonhomogeneous environment,a multiple strategy CFAR(MS-CFAR)detector is presented here based on the variable index CFAR(VI-CFAR)detector.By estimating the background noise and the clutter power in the reference window,the MS-CFAR detector adaptively selects one appropriate detector from the cell average CFAR(CA-CFAR),the approach cell CFAR(AC-CFAR)and the switching CFAR(S-CFAR).The simulation results show that the MS-CFAR detector provides better detection performance in the homogeneous environment and the nonhomogeneous environment including clutter edges and multiple targets,and performs robustly with anti-clutter edges and anti-multi targets while maintaining the good performance of VI-CFAR detector.
