摘要
该文对keystone变换进行了详细的分析,发现了其在处理越距离单元走动(MTRC)问题时的局限性,提出了一种新的MTRC补偿算法,通过实测数据和仿真数据对新方法进行了实验,实验结果表明了新算法的有效性。
The keystone transform and its applications in Inverse Synthetic Aperture Radar（ISAR） are analyzed.The localization character of keystone transform at MTRC（Migration Through Range Cells） is found,and a new method for solving MTRC is proposed.The new method is tested using practice measure data and simulating data.The experimentation results show that the new algorithm is effective.
