“…Coordinated acquisitions allowed the quasi simultaneous space and airborne measurements of large areas in the Weddell Sea [49]. -The measurement of ocean and atmospheric parameters was enabled by a joint acquisitions campaign between TanDEM-X and aircrafts in the Caribbean Sea within the context of the Harmony proposal for ESA's Earth Explorer 10 call [50].…”

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.

“…The processing of interferometric (and other) data related to topography is still a challenge, highlighting the need for the development of new open-source tools to support datasets that could come from innovative missions like ESA's Earth Explorer 10 candidate mission Harmony [25], [26]. Another solution would be to provide topography as a data product itself to facilitate the utilization of up-to-date topographic information by volcano observatories worldwide.…”

“…We also give an overview of the challenges in using TanDEM-X data to study active volcanoes. We close by advocating for the development of future SAR satellite missions capable of acquiring time-series topographic data, such as ESA's Earth Explorer 10 mission proposal "Harmony", which was submitted as Stereo Thermo-Optically Enhanced Radar for Earth, Ocean, Ice, and land Dynamics (STEREOID) by the scientific community [25], [26].…”

The TanDEM-X satellite mission has revolutionized DEM generation from spaceborne synthetic aperture radar. In addition to the primary objective of generating a consistent digital elevation model with global coverage and unprecedented accuracy, the mission has acquired time series of topographic data over several volcanoes, providing an excellent opportunity to test the use of this innovative dataset for volcano monitoring and research. We review the utilization of single-pass TanDEM-X data for studying various kinds of volcanic activity, such as basaltic lava flows, the formation and destruction of lava domes and related pyroclastic density currents, and subsurface magma withdrawal and intrusion. We then consider the uses of these data for hazard assessment and forecasting. Our goal is to highlight the importance of timely and repeated topographic information in volcanology, and to suggest the development of future spaceborne bistatic synthetic aperture radar satellite missions, such as ESA's Earth Explorer 10 candidate mission, 'Harmony.'

“…The BiSAR can also be applied in monitor, topography cartography, deformation detection, agriculture, classification, and so on [3,5,6]. In recent years, some new spaceborne bistatic and multistiatc SAR proposals are proposed, such as TanDEM-L [7], SAOCOM-CS [8], SESAME [9], MirrorSAR [10], and Harmony [11].…”

The deviation between the two oscillators in BiSAR systems will cause a residual modulation of echo signal. Therefore, the phase synchronization is an important issue that must be addressed for BiSAR systems. An advanced non-interrupted phase synchronization scheme is used for the LuTan-1 SAR satellite. The synchronization transceiver (STR) is designed for transmitting and receiving synchronization signals. In addition, STR mainly consists of master and auxiliary transceivers and switch module. Furthermore, the function and working principle of STR are introduced, and the detailed design of each part is described. The measured results are also evaluated to prove the performance of the STR. In addition, the phase synchronization accuracy is also demonstrated to verify the effectiveness of the non-interrupted synchronization scheme. The standard deviation (STD) of the residual phase is less than 0.3 degrees. The results have guiding significance for the synchronization unit design of LuTan-1 and the future BiSAR system.
