Abstract

This paper proposes a novel InISAR imaging method for space moving targets on a squint model using two antennas. In the pre-processing for range compression based on wideband direct sampling data, an adaptive matched filter containing speed is designed to carry out high-speed movement compensation that is essential for space targets. In order to reserve the phase history of each antenna, coherent processing for ISAR imaging is adopted. The corresponding size can be achieved by interferometric processing of the two complex ISAR images. Considering the condition may not be strictly satisfied, the influence of 3D motion and squint model is analyzed and a compensation method is adopted. Image distortion is corrected using coordinate transform. Simulation results confirm the effectiveness of the analysis and 3D imaging algorithm.
