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.
