摘要: 基于分布式衛(wèi)星SAR的正側視工作模式,該文建立了分布式衛(wèi)星SAR的回波模型,提出了通過雜波抑制進行慢速目標檢測和成像的算法。理論分析和仿真結果表明;該方法能有效地抑制雜波,提高運動目標的動態(tài)檢測范圍。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.
