Abstract：In this paper, ground slow-moving target imaging via airborne interferometric SAR/ISAR technique is investigated. Land clutter suppression and SCR improvement are achieved by range and cross-range two-dimensional high resolution of SAR. imaging and spatial domain cancellation of interferometer. True azimuth of moving target is determined using phase-comparison interferometer. Furthermore, high resolution image of the slow-moving target is obtained by IS AR processing. The block diagram and the operational principle of the airborne interferometric SAR./ISAR system are discussed in detail. Quantitative relations for SAR,, interferometer spatial domain cancellation, direction finding and ISAR processing are derived. Theoretical analysis and preliminary computer simulation reveal the validity of this technique.
