摘要

By exploiting the spatial-variant property of the inverse synthetic aperture radar (ISAR) imaging plane of a space target, interferometric ISAR (InISAR) can provide three-dimensional (3-D) images of space targets using fewer antennas than traditional InISAR imaging systems. This article analyzes InISAR imaging of space targets with monostatic radar. First, a more realistic ISAR imaging model for space targets is established, which adopts the rotation of the earth and can provide a mathematical apprehension of the movement of space targets in InISAR imaging. Next, a sequential phase unwrapping method for InISAR imaging of space targets with monostatic radar is proposed. Then, the performance indicator of this one-antenna InISAR system is provided with analysis of the impact of the influencing factors in InISAR imaging under different scenarios. Finally, numerical simulations are performed to validate the theoretical analysis and effectiveness of the proposed method.
