Monostatic ISAR signal processing: A new perspective

Abstract

Inverse Synthetic Aperture Radar (ISAR) derives its name from the fact that a synthetic aperture is formed by exploiting the movement of the target with respect to radar rather than by the movement of the radar platform radar. In ISAR applications, the target motion is usually not known and the target is also considered non-cooperative. An objective of the signal processing in ISAR is to obtain 2D or even 3D “image” of the target which represents the spatial distribution of various facets on the target that reflect electromagnetic waves when the target is illuminated by the radar.
