| Abstract | AbstractInverse Synthetic Aperture Radar (ISAR) imaging of targets with complex motions can be modeled as cubic chirps. Modified Discrete Chirp Fourier Transform (MDCFT) is used to process the cubic signal to obtain ISAR image in two dimensions (2D). In this paper, a new algorithm named Modified Fast Chirp Fourier Transform (MFCFT) is proposed. This algorithm gives accurate results as, and the computation time is very much reduced, compared to MDCFT. The simulation is carried out for ship and Airplane targets with different scattering points. The obtained results show an enhancement both in terms of resolution and computation time in the proposed method hence named Modified Fast chirp Fourier Transform. |
