A novel method for high speed moving targets ISAR imaging based on moving reference dechirp signal is presented in this paper. Firstly target track fitting is accomplished by utilizing assistant low-resolution range measurement results and envelope alignment for the target high-resolution range profiles. Then the target track is used for dechirp processing as a moving reference to accomplish motion compensation within a pulse period and coherent processing. Finally,Keystone transform is applied to correct the Migration Through Resolution Cells (MTRC) due to target rotation. Steps of this method for high speed moving targets are detailed. Simulations show the effectiveness of the new method.
