This contribution describes the improvement and extension of a 3-D inverse synthetic aperture radar (ISAR) imaging technique using a cylindrical scanning plane, first presented in [1]. The improvement is based on a modified focusing operator outlining the complete mathematical derivation, which is not given in the literature so far. Furthermore a fast and accurate extraction of the far-field radar cross section (RCS) is presented not only restricted on incident angles normal to the scanning plane but also comprises a larger range of elevation angles.
