Two kinds of restoration algorithms for wobbler switched data are
available: The EKH [Emerson et al. 1979] and shift-and-add algorithms. EKH is
much more elaborated and it enables to recover all the source structure as
long as the source stays undetected at the edges of the map along the
scanning direction. However, it works well only for relatively small source
size (i.e.
). Now, there are scientific projects
which search for point sources (at least sources whose size is smaller than
the half wobbler throw) on much larger sky areas. For these (i.e. search
for point sources on very large field of views), the shift-and-add
restoration method works well.
