  • Dechirping is an effective method for decreasing the bandwidth of input signals. For high velocity moving targets ISAR imaging, the residual phase arisen from dechirping processing and target moving can not be ignored. The theoretic model of phase signatures is derived thoroughly and the compensation methods are presented when dechirping technology is employed. In addition, the factors which influence residual phase and the precision of compensating are analyzed. According to the signatures of residual phase, a new compensation method is proposed in which the range alignment is applied to estimate the residual phase difference of adjacent echoes. Numerical simulation results illustrate the validities of proposed theories and methods.
