| 摘 要： | 逆合成孔径雷达的运动补偿技术是其成像技术中关键所在，而逆合成孔径雷达的运动补偿包括距离对准和相位补偿两方面，其中相位补偿在成像中起到了至关重要的作用，分别采用单特显点法、多普勒中心跟踪法和PGA自聚焦法对在最小熵包络对齐后的数据进行成像，仿真结果显示PGA算法在相位补偿算法中优势明显。

| Abstract: | The motion compensation is the key of the ISAR imaging, and the motion compensation approach of ISAR involves range realignment and phase compensation. Phase compensation takes a great part in ISAR imaging. The minimum entropy algorithm was used in range alignment, the single special point method, Doppler eentroid tracking method and PGA algorithm were introduced to complete phase compensation. The simulation results illustrated that the PGA algorithm is surpassing. |
