研究了机载高分辨二维逆合成孔径雷达（ISAR）对舰船目标侧视成像问题。使用一个简单的船舶运动模型，避免了使用先进的联合时频（JTF）变换。提出了一种鲁棒的处理方案，包括运动估计和校正、最佳处理时间和持续时间估计以及目标形状提取。我们强调的事实是，这种处理的鲁棒性导致一个单一的ISAR图像分析，没有合并的数据从一组雷达图像是必要的。
We address the problem of airborne high resolution two-dimensional inverse synthetic aperture radar (ISAR) side-view imaging of ship targets. Using a simple model of the ship motions avoids the use of advanced joint-time frequency (JTF) transforms. A robust processing scheme including motion estimation and correction, optimal processing time and duration estimation and target shape extraction are developed. We stress the fact that the robustness of this processing leads to a single ISAR image analysis and that no merging of data from a set of radar images is necessary.
