| 摘 要： | 包络对齐是逆合成孔径雷达（ISAR）平动补偿的关键技术之一。本文通过分析目标平动和转动对距离像的影响，建立了距离单元统计模型，并提出了一种基于该统计模型的包络对齐方法。该方法通过两个步骤完成包络对齐：利用目标回波数据提取各距离单元统计模型的参数；搜索使各距离单元的联合概率密度函数取得最大值的距离偏移量进行包络对齐。分析...

| Abstract: | Envelope alignment is one of the key technologies in inverse synthetic aperture radar(ISAR) translational motion compensation.Through analyzing effect of target translational motion and rotation in range profile,a range cells statistical model(RCSM) is built;and a new envelope alignment method was proposed based on the RCSM.The envelope alignment can be accomplished in two steps: firstly extract parameters of each range cell statistic model according to target echo data;then search and use the range displac... |
