摘要

描述了雷达目标一般运动的ISAR成像。ISAR成像可以看作是3D到2D的投影，并说明了ISAR图像投影平面的重要性。对于一般运动，在使用FFT处理时，ISAR图像经常会被涂抹。采用时频法对这类图像进行分析，形成清晰的图像。一个给定的模糊图像被证明是在比例和在投影平面方向的变化的结果。

ISAR - radar imaging of targets with complicated motion

ISAR imaging is described for general motion of a radar target. ISAR imaging may be seen as a 3D to 2D projection, and the importance of the ISAR image projection plane is stated. For general motion, ISAR images are often smeared when using FFT processing. Time frequency methods are used to analyze such images, and to form sharp images. A given smeared image is shown to be the result of changes both in scale and in the projection plane orientation.
