摘要

摘要: 该文介绍了应用匹配傅里叶变换检测SAR中运动目标的方法。文中讨论了信号模型、检测方法，并进行了仿真研究。仿真和实际的SAR数据中运动目标检测处理结果表明：在雷达平台运动速度被补偿，且脉冲压缩之后，再应用匹配傅里叶变换进行运动目标检测是比较好的检测方法；在一定的条件下，也可以比较相邻SAR图像中强点间相对位置的变化来判断运动目标。

Abstract: In this paper, a method of detecting moving targets in SAR using the match FourieT transform is introduced. The signal model and the detecting method are discussed and simulations are performed. The results of the simulations and the practices of detecting moving targets in SAR data show that when the velocity of the radar platform is compen-sated and pulses are compressed, the moving targets are easily detected using match Fourier transform, and under certain conditions, the moving targets may be detected depending on the relative position of strong points in contiguous SAR image.
