Fig. 4
From: Formulation of a generalised switching CFAR with application to X-band maritime surveillance radar
Performance of the three detectors in homogeneous horizontally polarised clutter, and with up to two interfering targets. The right subplot is an enlargement of a component of the left subplot, to examine performance in closer detail. Detector (16) is referred to as CA-CFAR in this figure, while (17) is called OS-CFAR to reflect the fact that they are CFAR detectors. The switching detector (18) is denoted SW in the figure. If subjected to interference, the respective detector is marked appropriately as outlined in the legend
