  • Abstract
    Inverse synthetic aperture radar (ISAR) imaging with stepped-frequency chirp signal (SFCS) is simulated by de-chirping processing. Time-frequency analysis and image processing techniques are applied together for motion compensation. Detailed algorithm steps and imaging simulation for high-speed moving target with an acceleration as large as 30m/s2 are presented. Results indicate that SFCS signal has an much better performance than stepped-frequency continuous wave signal for imaging of target with ultra-high speed.
