空中客车和Hisdesat流程首先Terrasar-X / PAZ雷达干涉图
Airbus Defence and Space and Hisdesat Servicios Estratégicos have generated the first joint TerraSAR-X / PAZ Radar Interferogram. This milestone demonstrates the missions’ capacity for cross-sensor interferometry, which is extremely challenging to process. Interferograms are typically used to derive the topographic elevation and deformation of the Earth’s surface, and are created using at least two different images acquired on different dates. This flattened Cross-Sensor Interferogram has been created from a mixed image pair with 4 days temporal separation acquired by TerraSAR-X and PAZ (StripMap scenes from 22 and 26 November 2018). The area covers the oil and gas production site Burgan (Kuwait) and parts of the Persian Gulf. The oil field is the world's largest sandstone oil field with the total surface area of about 1,000 km².
快速地变形监测
由于PAZ定位在与Terrasar-X和TandeM-X的同一轨道中，并且具有完全相同的地面条声和采集模式，它们全部三种高分辨率SAR卫星星座，由Hisdesat和空中客车共同利用。随着PAZ的推出，观察重复周期已经除以一半，这改善了能够危及生命和基础设施的快速地面变形现象的监测。
“这是一个实现implem的重要一步entation of our TerraSAR-X / PAZ Radar Constellation. The level of accuracy obtained with this interferogram is a guarantee for our customers to continue to rely on the high quality standard we have set withTerrasar-X.and串联X.但是，具有改善的监测能力，“空中客车防御和空间，智能化的生产和雷达星座经理Hanjo Kahabka说。
“At Hisdesat we are very proud of reaching this milestone. Interferometry is one of the most technically demanding applications and thanks to this successful joint exercise with Airbus we have not only demonstrated the top performance of our PAZ satellite but its full compatibility with TerraSAR-X and TanDEM-X. Now operation in constellation can become a reality and we will be able to provide to our customers full set of images and services with the constellation,” said Miguel García Primo, chief operating officer at Hisdesat.
