Some researches on the problem a-bout moving target high - resolution range profile ( HRRP) synthesizing method for MIMO radar with OFD - LFM signal are carried out in this paper. First of all, the imaging geometric figure of MIMO high - resolution radar with OFD -LFM signal is established. On the basis of that, a new moving target HRRP synthesizing method based on phase compensation for MIMO radar with OFD — LFM signal is proposed via strictly theoretical deduction and detailed principle demonstration. The moving target HRRP can be synthesized effectively by using the proposed method , because the orthogonality among the different sub - pulses is utilized. What's more, the condition of unwrapped HRRP is also obtained successfully. The simulation results validate the effectiveness of the proposed method.
