FIGURE 6.27 Comparison of conventional, “smallest-of,” and “greatest of”
cell-averaging CFAR with multiple targets and a clutter edge: (a) CA and
SOCA CFAR, (b) CA and GOCA CFAR.
The CA CFAR masks the weaker of the two closely spaced targets and
also fails to detect the target near the clutter edge, but does not exhibit a false
alarm at the clutter edge in this instance. The SOCA threshold, in contrast,
