In order to get linearly modulated frequency stepped radar image of maneuvering target in low SNR, a new accumulation imaging method based on Radon-fractional ambiguity function (RFRAF) was proposed. Based on the characteristics of the maneuvering target's linearly modulated frequency stepped radar echo signals, the target's echo signals were matched and accumulated in the RFRAF domain in the pulse repetition period, and the target's moving parameters were estimated by peak searching of the RFRAF spectrums. Then compensation function was constructed to compensate the maneuvering target motion, so as to obtain the accurate ISAR image. Computer simulation results showed that the proposed method could be robust in low SNR.
