Abstract :
The assumption, that baseline keeps invariant during the imaging time, is established acquiescently in traditional interferometic ISAR (InISAR) imaging using L-type three antennas structure. However, the baseline often changes more or less in some cases. This paper analyzes the effect of the baseline length variation on interferometic image reconstruction. Besides, the compensated variation range of baseline length is given. In order to eliminate the effects of baseline length variation on three-dimensional imaging, a compensation method of interferometric phase is proposed. Simulation results show the effectiveness of the proposed method.
