TanDEM-X: 10 Years of Formation Flying Bistatic SAR Interferometry

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2021
On June 21, 2010, the TanDEM-X mission was launched and opened a new era in spaceborne radar remote sensing. The first formation flying radar system was built by extending the TerraSAR-X synthetic aperture radar (SAR) mission by a second, TerraSAR-X-like

Towards the analysis of the performance measures of heterogeneous networks by means of two-phase queuing systems

open access: yesDiscrete and Continuous Models and Applied Computational Science, 2021
Due to a multistage nature of transmission processes in heterogeneous 4G, 5G mobile networks, multiphase queuing systems become one of the most suitable ways for the resource allocation algorithms analysis and network investigation.

Benefits of a second tandem flight phase between two successive satellite altimetry missions for assessing instrumental stability [PDF]

open access: yesOcean Science
Five successive reference missions, TOPEX/Poseidon, Jason-1, Jason-2, Jason-3, and more recently Sentinel-6 Michael Freilich, have ensured the continuity and stability of the satellite altimetry data record. Tandem flight phases have played a key role in

TanDEM-X: first scientific experiments during the commissioning phase [PDF]

open access: yes, 2010
In this paper new and innovative techniques during the commissioning phase of TanDEM-X will be presented that are firstly demonstrated on a satellite platform. The focus is on the secondary goals of TanDEM-X that are assigned for the third year of the mission time life due to the tight schedule for the acquisition of the highly accurate global digital ...

Compact dynamic optical isolator based on tandem phase modulators

open access: yesOptics Letters, 2019
Non-magnetic dynamic optical isolators, constructed from modulators, provide a complementary metal oxide semiconductor (CMOS)-compatible approach to optical isolation in integrated photonics. The size of these isolators is strongly constrained by both the frequency and strength of optical modulation.
