中文摘要：
针对OFD—LFM信号体制MIMO雷达运动目标的高分辨距离像（HRRP）合成问题展开了相关的研究工作，首先给出了OFD—LFM信号体制MIMO高分辨雷达成像的几何关系图，在此基础上，通过严格的理论推导和详细的原理论述，提出了基于相位补偿的OFD—LFM信号体制MIMO雷达运动目标的HRRP合成方法，该方法利用了OFD—LFM信号中各子载波信号之间的正交性，可有效地合成出运动目标的HRRP。此外，还进一步分析了HRRP不发生卷绕的条件。仿真结果证明了本文方法的有效性。
英文摘要：
The Multiple - Input Multiple - Output （MIMO） radar imaging with OFD - LEM has an important and practical value for non -cooperative moving targets detection and recognition. 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 de- tailed principle demonstration. The moving target HRRP can be synthesized effectively by using the proposed meth- od, 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.
