| 摘 要： | 由于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)成像造成较大的困难。当多目标间存在相对运动时,直接利用常规补偿方法通常得不到满意的结果。该文建立了目标相对运动的模型,分析了相对运动对成像的影响,提出了一种新的相对运动补偿算法。该算法对存在相对运动的目标在距离上利用Keystone变换进行分离,提取相对运动目标的回波,分别利用Autoclean算法进行运动补偿。模拟和实测数据的成像结果表明,该算法是可行的。

| Abstract: | Inverse synthetic aperture radar (ISAR) imaging of the non-cooperative maneuvering multi-target is a challenging task due to its time-varying orientation and the relative motion among targets. Conventional motion compensation methods assume that targets' positions are almost fixed during the imaging time. In this paper, the model of relative motion targets is established and the effect of relative motion for ISAR image is analyzed. A new algorithm for relative motion compensation based on Keystone transform... |
