摘　　要：针对主星伴随小卫星SAR的干涉几何关系,在分别给出其测高和测速原理的基础上提出了多基线干涉提高测高精度的方法和利用对称性解耦合提高测速精度的方法。利用仿真结果对两种方法的有效性进行了验证。最后将两种方法综合运用到分布式小卫星的空间编队构形中,给出了一种空间编队构形,对编队构形优化设计具有重要意义。Aiming at the interferometry geometry relationship of master and distributed small satellite SAR system,two methods to enhance height precision on the basis of satellite Saar s recent height and speed principles,one is multi-baseline interferometric method,and the other is symmetrical eliminated phase method.And then test two methods validity through emulation results.Finally wield two methods in distributed small satellite s space configuration to research a new configuration which is with great importanc...
