TanDEM-X is a formation flying interferometer consisting of two SAR satellites. Together they acquire bistatic SAR data of the Earth in order to generate a global Digital Elevation Model as well as individual scientific interferometric data sets on user request. This paper gives an overview about ten years of acquisition and formation planning for the TanDEM-X mission. This planning on the one hand includes the derivation of the formation, i.e. the 3D distance between both satellites in orbit. On the other hand it needs to consider the regions of interest and the mission, satellite, and instrument constraints in order to effectively plan the bistatic acquisitions. During the ten years in operation TanDEM-X successfully completed various mission goals during dedicated mission phases. All these phases, their characteristics as well as the scientific and commercial outcome are described in detail.

“…TerraSAR-X and TanDEM-X have been operating in the pursuit monostatic mode only a few time periods, the first one was during the commissioning phase in 2010 and the second was from the end of 2014 until the beginning of 2015 as the first part in the science phase of the TanDEM-X mission. The pursuit monostatic mode [9] requires TerraSAR-X and TanDEM-X to fly in an identical satellite orbit in space and separated few seconds in time. During the commissioning phase this time separation was about 2.5 seconds and in the science phase it was 10 seconds.…”

Change Detection for Monostatic Pursuit SAR GMTI—Theories and Experimental Results

Monostatic pursuit refers to the operating mode formed by two monostatic SAR systems that follow an identical orbit with a separation in time of several seconds. The detected changes between SAR scenes with several seconds time difference are most likely the changes caused by ground moving targets. Hence, this operating mode opens an opportunity to detect ground moving targets by SAR change detection methods. The paper investigates this possibility to detect ground moving targets using change detection and to combine change detection and GMTI for GMTI. In this combination, a GMTI method will help to classify the detected changes obtained with a change detection method. Some GMTI results are provided in the paper based on the measurements in the monostatic pursuit mode with deployed targets, conducted by TerraSAR-X and TanDEM-X in Sweden in early 2015.

“…From October 2014 to February 2015, the German synthetic aperture radar (SAR) satellite formation TanDEM-X [1] was operated in pursuit monostatic (PM) mode, an innovative imaging mode allowing to acquire interferometric SAR data with increased spatial and temporal baselines [2,3]. With an alongtrack distance of 76 km between both satellites (corresponding to a temporal baseline of about 10 s), the temporal decorrelation was expected to remain small for most terrain types -except for water areas, which tend to decorrelate much Preprint submitted to ISPRS Journal of Photogrammetry and Remote SensingJanuary 8, 2019 arXiv:1901.01548v1 [eess.IV] 6 Jan 2019 faster due to the fast-changing wave appearance.…”

This is the pre-print version, to read the final version please go to ISPRS Journal of Photogrammetry and Remote Sensing. This article investigates the potential of nonlocally filtered pursuit monostatic TanDEM-X data for coastline detection in comparison to conventional TanDEM-X data, i.e. image pairs acquired in repeat-pass or bistatic mode. For this task, an unsupervised coastline detection procedure based on scale-space representations and K-medians clustering as well as morphological image post-processing is proposed. Since this procedure exploits a clear discriminability of "dark" and "bright" appearances of water and land surfaces, respectively, in both SAR amplitude and coherence imagery, TanDEM-X InSAR data acquired in pursuit monostatic mode is expected to provide a promising benefit. In addition, we investigate the benefit introduced by a utilization of a non-local InSAR filter for amplitude denoising and coherence estimation instead of a conventional boxcar filter. Experiments carried out on real TanDEM-X pursuit monostatic data confirm our expectations and illustrate the advantage of the employed data configuration over conventional TanDEM-X products for automatic coastline detection.
