Imaging that exploits multipath scattering from point scatterers

This paper develops a method for making an image of an object when there are extra point-like scatterers in the environment. Once the location of these scatterers is known, they can be exploited in the imaging process. Here the extra point scatterers are assumed to lie between the sensor and the object of interest. A single-scattering model is used for the object itself. Detailed analysis is carried out for the case of a single extra scatterer in the foreground; the extension to the case of many scatterers is expected to be similar.
