旋转目标一维和二维成象处理之间的关系

本文针对旋转目标逆合成孔径雷达成象(ISAR)处理中的距离—多卜勒(R-D)处理和由投影层析成象(CT)处理两种基本方法,研究了它们之间的基本关系,讨论了它们各自的处理特点和处理能力。结果表明这两种基本方法其实质是一致的,只不过各自有其应用条件和特点。本文研究的目的在于更深刻地认识现有的一些ISAR成象处理方法的内在联系,为寻求新的、实时、高分辨的ISAR成象处理方案探索途径。

Relation between 1--D and 2--D imaging methods for rotating objects

The relation between the range-doppler processing and tomography processing meth- ods in inverse synthetic aperture radar imaging for rotating objects is discussed, and their respective processing features and ability studied. The results show that these two methods are virtually consistent in nature but have their own application condition and features, Our purpose is to understand the relations among some present ISAR imaging processing methods deeply to develop new ISAR imaging algorithms with real-time and high resolu- tion properties.
