r(.x, y) =

and r,-(x, y) is assumed the individual reference pattern centered at (a- t, ft,), and
vv(i') represents an iterative feedback weight coefficient for each r,(.x, y) with an
initial weight value equal to 1. By joint-transforming t(x, y), the corresponding
JTPS is given by

JTPS = \R(p, q}\ + |0(p, q)\ + R*(p, q)0(p, q) , q).
In the feedback iteration, JTPS is nonlinearized and inverse-transformed to
obtain the output correlation, for which the feedback coefficient w'(z') was
