In this paper the new application results of Linear and NonLinear Fusion Constant False Alarm Rate (LF-CFAR and NLF-CFAR) detectors are presented. Detection of very close targets per azimuth and per range is considered. The entire simulation is done on the basis of the software defined radar receiver. All used CFAR detectors are implemented in mentioned model of the radar receiver. Also, a comparative analysis in detection of very close targets of fusion CFAR detectors versus single CA-CFAR (Cell Averaging CFAR), OS-CFAR (Ordered Statistic CFAR) and TM-CFAR (Trimmed Mean CFAR) is done. The targets are simulated in a real clutter

Key words: detector, detection, target acquisition, radar, software defined radar, clutter.
