A time synchronization is presented which fulfills the well known task of synchronizing transmitter and receiver, but also helps to avoid transmissions in periods of rough noise conditions. The synchronization method is based on a maximum-likelihood approach that makes use of the phase of the mains voltage. Further improvements concern the codes used for the transmitted sequences as well as the combination of the information within both FSK carrier-frequencies in terms of equal gain and maximum ratio combining. Additionally an approach for a lowcomplexity frame synchronization is presented.

    The paper presents an approach for target position recovery from frequency modulated continuous wave (FMCW) radar data. The presented algorithm is, in contrast to many established techniques, able to use snapshots taken from arbitrary positions. The presented technique can be applied to imaging as well as localization applications. The basis of the approach is a compressed sensing based algorithm called normalized iterative hard thresholding (NIHT). To prove its capabilities it is evaluated by simulation over a wide range of signal bandwidths and base frequencies.

Whereas many publications deal with research on temperature compensation of single components, this paper describes the influence of the ambient temperature on the entire RF front end of the sensor system, a 61 GHz Six-Port interferometer. After presenting the measurement system, the temperature influences on the four output voltages and the consequences for the measurement results are analyzed.

    @inproceedings{reissland2017,
    abstract = {In highly automated industrial applications radar sensor systems already play an important role. For future applications, good knowledge about the three-dimensional environment of physically acting industrial systems will be beneficial, if not necessary. For this reason, the use of distributed radar systems to gain precise knowledge of the systems environment and its work pieces is proposed.

    In the literature only few approaches for three-dimensional radar target recovery in the short range can be found. Furthermore, these approaches presume different kinds of regular patterns in which the radar sensors must be placed. This is obviously contrary to the requirements of e.g. industrial robots which can be moved on arbitrary trajectories. The most challenging problem when it comes to target recovery from randomly distributed radar sensors is the high computational effort which has to be spent.

    In this work an algorithm is presented which aims at recovering several point targets from as few as possible radar measurements. The whole work is based on simulations and analytical considerations. Each radar uses well-known frequency modulated continuous waveform signals to gain information in range direction. As stated in the title the recovering is carried out by a compressed sensing algorithm. To use this algorithm the whole problem has to be transformed into a linear system of equations, small enough to be solved by commercially available computers in an amount of time which is suited for the application. This linear equation eventually consists of the received radar signals, a measurement matrix and the reflectivity of assumed targets located in a-priori defined voxels. As the number of voxels which have to be taken into account increases drastically with the desired resolution, an iterative approach had to be developed to limit the algorithms requirements in terms of computational effort. Finally, different suited recovery algorithms were compared in terms of robustness.}, author = {Reißland, Torsten and Koelpin, Alexander and Weigel, Robert}, language = {English}, booktitle = {Kleinheubacher Tagung}, cris = {https://cris.fau.de/converis/publicweb/publication/112596924}, year = {2017}, month = {09}, day = {25}, eventdate = {2017-09-25/2017-09-27}, faupublication = {yes}, keywords = {Radar,Compressed Sensing,Imaging}, peerreviewed = {Yes}, title = {Target Recovery from Randomly Distributed Radars using Compressed Sensing Techniques}, type = {Abstract zum Vortrag}, venue = {Miltenberg, Germany}, }
