| 摘 要： | 本文针对ＩＳＡＲ外场实验数据，提出一套改进的运动补偿方法。首先用回波动态范围压缩的积累互相关方法进行补偿，再用相位梯度自聚焦算法进一步提高相位对准的精度。用这种方法对实验ＩＳＡＲ外场数据进行处理，得到了高质量的成像结果。

| Abstract: | This paper presents an improved method of motion compensation for ISAR. After the compensation based on the dynamic range compression and accumulated cross correlation, phase gradient autofocus(PGA) is used to improve the accuracy of phase compensation. The high quality images have been obtained for the data acquired from outside experiments. |
