TerraSAR-X Reveals the Smallest Changes

The Al-Azraq Airbase in Jordan is strategically located near the border with Syria and Iraq and is increasingly being used in the U.S. led operations against ISIS. 
Since 2017 TerraSAR-X has been monitoring the airbase at an interval of 11 days and this has allowed for the quick identification of infrastructure changes and continued expansion of the airbase. Automatic change detection processes allow for a quick identification of infrastructure changes and investigation of activities on the ground. Later images showed preparation of construction work on a new access road and images, acquired in early 2018, confirmed the progress of construction works including a new entry point to the base.
 
 
TerraSAR-X Reveals the Smallest Changes
The ability of Airbus SAR sensors to identify and measure even subtle changes in the target area provides a very powerful tool for detailed military and/or environmental monitoring applications.
 
While radar satellite data is an ideal tool to reliably identify infrastructure changes, the real benefit of SAR is revealed when subtle surface changes are identified that might go unnoticed when using only optical imagery yet can provide crucial insights about activities on the ground. 
 
With the recent launch of the Spanish PAZ satellite (an exact rebuild of TerraSAR-X, operated by Hisdesat), the monitoring capabilities of the Airbus SAR constellation will be further enhanced. PAZ has been placed in the same orbit as TerraSAR-X and TanDEM-X and will reduce the revisit time to 4/7 days once fully operational.
 
The constellation’s capacity, alongside with optical images, empowers both data-hungry services and time-critical missions, enabling a broad array of applications including detection and identification of objects and their changes e.g. for image intelligence applications, or monitoring of surface movements as well as object movement.
