This paper deals with generalized ISAR geometry and image reconstruction technique. Two-dimensional (2-D) Inverse Synthetic Aperture Radar (ISAR) scenario is depicted in a two-dimensional radar signal registration plane. The arbitrary movement of the object is decomposed into two components: radial displacement of the object's geometric center and rotational movement around it. It is proven that the demodulated ISAR signal, reflected from the target during aperture synthesis, could be considered as 2-D Fourier transformation of the image function, corrected by an exponential phase term and therefore, the image function can be extracted by 2-D inverse Fourier transformation. Numerical experiments validating the aforementioned theoretical statements have been carried out.
