When a target undergoes complex 3-D motions, focused inverse synthetic aperture radar (ISAR) images cannot be obtained using any motion compensation algorithms. To address this problem, we propose a method to determine the suitable frame time and length for 2-D ISAR imaging, which exploits phase nonlinearity and discrete polynomial phase transforms. In simulations and experiments, we observed that the proposed method can efficiently select proper frame times and lengths for 2-D ISAR imaging.
