Abstract: 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.

Key words: keystone transform, time frequency coupling, Migration Through Range Cells(MTRC)
