Based on the side-looking mode SAR of distributed satellites SAR system. This paper gives the mathematical model of SAR echo signal, and proposes a imaging algorithm of the single satellite SAR of distributed satellite SAR and imaging algorithm of distributed satellite SAR system by beamforming and multilook. The results of theory analysis and simulation show that the algorithm can enhance SNR and suppress the speckle noise of resulted image without changing the resolution of SAR image, improve images quality.
