Abstract
A case study of a modified Inverse Synthetic Aperture Radar (ISAR) imaging technique for different target geometries in the Far Field RCS measurement Compact Range is presented. The processing applied to the experimental data is a combination of two high resolution processes: dev of High Range Resolution profile (HRR) in the down range using stepped frequency waveform covering a total band of 4GHz, and the development of high resolution profile in cross-range is achieved using ISAR technique. The manuscript shows the use of Polar reformatting algorithm with Shannon reconstruction technique for correcting migration through resolution cells to obtain a better focused image of rotating targets.
