| 摘 要： | 针对分布式卫星SAR系统的正侧视工作模式，建立了雷达信号的回波模型，提出了利用修改的距离－多普勒（RD）算法进行单个星载SAR成像的算法及波束形成合成分布工卫星SAR图像的算法。理论分析和仿真结果表明：利用该算法能提高图像的信噪比，使图像质量得到提高。

| Abstract: | Based on the side looking SAR mode of distributed satellite SAR system, this paper gives the mathematical model of SAR echo signal and puts forward a imaging algorithm of the single satellite SAR by the modified RD algorithm and a beamforming imaging algorithm of distributed satellite SAR system. The results of theoretical analysis and simulation show that this algorithm can enhance SNR of resulted image and improve quality of the image. |
