Abstract
According to mapping ways the InSAR satellites include repeated orbit InSAR,dualantenna InSAR and distributed InSAR.The way of dual-antenna InSAR can achieve higher interferometry mapping efficiency.This paper focuses on spaceborne dual-antenna InSAR,researching the system technologies,such as the relationship between the height of orbit and the altitude mapping precision,the payload operation mechanism and altitude mapping precision,and the impact on interferometry performance by the jitter of the antenna arm.Then it analyzes the key technologies of the spaceborne dual-antenna InSAR.关键词
