| 摘 要： | 逆合成孔径雷达的运动补偿问题已有很多讨论,并在实际中得到成功的应用。运动补偿是ISAR成像技术的关键,分两步进行：包络对齐和相位校正。本文从全局效果出发,研究了平均包络最小熵包络对齐法和最小熵相位校准法的原理及算法实现,并对仿真数据进行成像处理。实验结果表明,平均包络最小熵法和最小熵相位校正法在ISAR雷达的运动补偿算...

| Abstract: | The problem of motion compensation in ISAR imaging has been discussed by many researchers.The motion compensation is one of the key technologies of ISAR imaging,and involves range realignment and phase compensation.This paper studied the principle and algorithm of the minimum entropy average range profile and the minimum entropy phase compensation from the overall situation,and simulated the imagine processing.The results showed that the minimum entropy average range profile and the minimum entropy phase compensation in ISAR motion compensation algorithm a significant effect,which can ensure good alignment accuracy and high computing efficiency,and also has good robustness. |
