Abstract: In this paper we describe software models of CA-CFAR, OS-CFAR and the TM-CFAR detectors in the receiver of the software defined radar. A comparative analysis of these CFAR detector models in terms of detection of radar targets in conditions of real clutter is performed. Software models of CFAR detector are implemented in MATLAB.

Key words: CFAR, software radar, target, real clutter.
