  • Based on the principles of ISAR and interferometric observation, a three-dimensional (3D) imaging method of Interferometric ISAR (InISAR) is developed. Making use of compensation of the resultant angular motion parameters for the echoes in the raw data level, two complex images from interferometric antennas are, sequentially, co-registered. A 3D image of a moving target is reconstructed from the spatial coordinates of these scatter centers of the target. Also, a stretch processing of LFM signal to remove the background clutter is discussed. This method is simple and easily implemented in engineering. Simulations show that this 3D imaging method works well even for a moving target in strong clutters.
