ISAR成像用于描述雷达目标的一般运动。ISAR成像可以看作是从3D到2D的投影，并阐述了ISAR图像投影面的重要性。对于一般的运动，当使用FFT处理时，ISAR图像经常会被模糊。使用时频方法对这些图像进行分析，并形成清晰的图像。给定的涂抹图像显示为尺度和投影面方向改变的结果。
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.
