A cooperation earth observation model constituted by two SAR satellites and one optical remote sensing satellite is proposed. In this model, the optical remote sensing satellite orbit plane locates in the middle of two SAR satellites, and two SAR satellites observe the same ground area from two sides of the optical satellite respectively. However, because of the influence of earth curvature, not only...
Multi-baseline INSAR is a kind of technology that obtains terrain height information using multiple SAR images, therefore, it has a better performance than single-baseline INSAR. There are primarily two methods to increase the accuracy of terrain height estimation. One increases the quality of the interferometric absolute phase image by utilizing several single-look complex images. The other decreases...
The DSS-INSAR (distributed small satellite INSAR) applies the interferometry to the carrier platform which is made up of small satellites flying in a certain formation. It aims to retrieve DEM (digital elevation map) with quite high precision globally. In fact, every small satellite in the flying formation is dynamically circling around a reference central point along a certain track. Therefore, the...
