Abstract

To high resolution spaceborne SAR, one problem is inevitable that as to targets with elevation downs in one scenario, their imaging quality will decline after processing with imaging algorithm. SAR images are confined to two-dimensional domain and it's hard to reflect targets' height property. Instead, target A with some height is projected to target B with no height while A and B are in the different range door but with the same slant range from the satellite. Doppler parameters of B are used to image A due to the two-dimensional limitation and then azimuth defocusing and range location shift will occur. Target height can be regarded as one error source. In this paper, imaging quality of targets with height error is improved through self-focusing method among three-step focusing algorithm as to high resolution sliding spotlight SAR. Experiment results show that it's effective.
