From a ``plane-wave'' viewpoint, the image point in the angle-domain
is determined by the intersection of the lines passing through the
points and tilted by
and
. This interpretation
is consistent with the one for flat reflectors illustrated in Figure 3.

The geometric interpretation of the angle is
illustrated in Figure 4. According to
equation (10), the depth of the
image point in the angle-domain
is given by the intersection
of the two lines passing through the points
and tilted by
