| 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 pro-posed.The new method is tested using practice measure data and simulating data.The experimentation results show that the new algorithm is effective. |

| Keywords: | keystone transform time frequency coupling Migration Through Range CelIs(MTRC) |
