Abstract

This paper investigates the possibility to combine passive ISAR imaging of a maneuvering ship over different frames using digital video broadcasting-satellite (DVB-S) as illuminators of opportunity. First, the image point spread function (PSF) in the target fixed reference system is analytically derived, allowing to characterize the resolution properties in a domain independent on the particular frame. Then, a few preliminary experimental results are provided considering a turning ferry, showing that the combination of multiple frame images can increase the amount of information enhancing the ship classification capability.
