摘要 分布式小卫星SAR由于其基线长达数百米以上,采用沿航迹干涉测速时,速度模糊非常严重.本文分析了沿直线排列的小卫星编队利用多基线和多工作频率来消除测速模糊的方法;讨论了速度方向模糊问题;简要地分析了空间立体编队的分布式小卫星SAR消除速度模糊的方法. Because the length of baseline is more than several hundred meters ot the distributed small satellites SAR, the velocity ambiguity is serious when using along-track interferometry （ATI）. This paper analyzes the multi-baseline and multi-frequency of radar transmitting based on along-track linear formation for eliminating the ambiguity of velocity measurement. The ambiguity of velocity direction is also discussed and the deblurring methods for spatial three-dimensional satellites formation are studied in brief.
