【摘要】 非合作的机动多目标相对于雷达射线的姿态是时变的,而且目标间可能存在相对运动,给逆合成孔径雷达(ISAR)成像造成较大困难。针对此问题建立目标相对运动的模型,提出一种相对运动补偿的算法,在运动补偿的基础上对运动目标进行二次补偿,消除相对运动的影响。模拟和实测数据的处理结果说明,当相对运动目标和其它目标在距离上能分离时,该算法是可行的。更多还原

【Abstract】 Inverse synthetic aperture radar(ISAR) imaging of non-cooperative maneuvering multi-target is a challenging task due to its time-varying orientation and the relative motion among targets.This paper constitutes the model of relative motion targets,and proposes an algorithm for relative motion compensation.The imaging results using simulation and real data show the effectiveness of the new method when the target having relative motion can be separated with other targets in the dimension.更多还原
