Multistatic ISAR - chances and challenges

This paper is concerned with recent and future developments in the field of multistatic radar imaging of moving targets. It briefly reviews traditional monostatic ISAR imaging and identifies its drawbacks. We then present ideas, some of them have meanwhile been verified in experiments, how a multistatic setup can overcome some of these problems. Clearly, a multistatic setup leads to increased complexity and new problems. We display these new problems and present approaches to solve some of them. We use mind maps to illustrate the context. Multichannel techniques like interferometric or polarimetric ISAR are out of the scope of this paper.
