Across-Track Interferometry
A consistent and reliable DEM data set with global coverage and DTED-3 standard is an important information for a variety of on-going research areas and will allow new scientific applications to be developed. Examples are:
Along-Track Interferometry
Along-track interferometry will allow innovative applications to be explored. Along-track interferometry can be performed by the so-called dual-receive antenna mode (ca. 2.4 m along-track baseline) and/or by adjusting the along-track distance between TSX-1 and TanDEM-X to the desired value (up to 4 phase centers). By means of newly developed orbit concepts, the along-track component can be adjusted from 0 to several kilometers. The combination of the two different along-track baselines will be explored for moving target detection (MTI) and traffic monitoring applications. The following sub-groups have been defined for along-track interferometry:
New Techniques with Bi-Static SAR
The TanDEM-X mission will provide the remote sensing scientific community with a unique data set to exploit the capability of the new bi-static radar techniques and to apply these innovative techniques for enhanced parameter retrieval:
