| 摘 要： | 利用一组小卫星进行编队飞行,它们之间协同工作来完成某一特定任务,其功能和可靠性远远超过一颗单独的大卫星,因而具有高的性能/价格比.对于单颗卫星SAR,其横向分辨率与测绘带宽相矛盾,而采用分布式小卫星SAR,可使这一矛盾得到解决.本文主要研究如何通过信号处理化解多普勒模糊,实现理论最高分辨率的问题.

| Abstract: | The distributed satellites are clusters of small satellites that cooperate to perform multiple space mission functions,and its functions and reliability are well beyond a larger,single satellite.Since the concept was formulated,there are several research efforts looking for the possibility of using a group of small satellites to do mission functions.Beam nulling is used for resolving Doppler aliasing and achiering full resolution SAR imaging.Simulation results prove this method preferable. |

| Keywords: | distributed small satellites synthetic aperture radar radar resolution beam nulling |
