摘要: 基于分布式卫星SAR的正侧视工作模式,该文建立了分布式卫星SAR的回波模型,提出了通过杂波抑制进行慢速目标检测和成像的算法。理论分析和仿真结果表明;该方法能有效地抑制杂波,提高运动目标的动态检测范围。Abstract: Based on the side-looking SAR mode of distributed satellites SAR system, this paper gives the mathematical model of radar echo signal of distributed satellite SAR, and proposes a detecting and imaging algorithm of the moving targets with low velocity by suppressing the ground clutters. The results of theory analysis and simulation show that the algorithm can suppress the ground clutters efficiently, and enhance the detecting ranges of moving targets.
