Abstract

In ISAR imaging, a Point Scatterer mechanism is frequently invoked, implicitly or explicitly. This paper looks at which categories of EM scattering give rise, in effect, to point scatterer type of return. We find that there are a number of different types of point scattering returns. Such an examination is also relevant to the adequacy of point scatterer models (PSM) which have sometimes been used for modeling aircraft or ships. Another important question is how point scatterers can be recognized as such. Finally the impact of point scatterer assumptions on ISAR autofocus methods will be briefly assessed.
