In order to reduce the computational cost in the current MIMO-ISAR back projection imaging algorithm, a fast algorithm based on FFT is proposed for MIMO-ISAR back projection. First, we establish the reflected wave signal model for MIMO-ISAR imaging. The approximate representation of linear change of phase compensation factor is provided. Second, the constraints of the conversion from non-linear phase compensation factor to linear compensation factor is given. Finally, an efficient algorithm for MIMO-ISAR back projection based on FFT is achieved. Simulation results show that compared with traditional methods, the proposed algorithm reduces the computational cost greatly.
