| 摘 要： | 由于传统的ISAR成像算法采用FFT，不能够很好地对机动目标成像，图像模糊，难以辨认，提出采用在时间和频域同时具有高分辨率的时频变换—Gabor变换来替代FFT作方位向的处理，得到目标的距离瞬时多普勒图像，实测数据结果表明，该方法得到的图像结果较好。

| Abstract: | As FFT is used in traditional ISAR algorithms,it is bad to get the ISAR images of maneuvering targets. Those images are fuzzy and difficuh to recognize. FFT is replaced by time - frequency transformation-Gabor transformation with high resolution in both time and frequency domains to deal with cross range. Thus range - instantaneous Doppler images of maneuvering targets are got. The imaging result using real data shows that the images are better than those got by R- D algorithms. |
