Internships

Applications can be sent throughout the year to one of the contacts below. It should be kept in mind that:

• internships should be at least four weeks in duration
• training is on-the-job in current projects
• your application should include the dates of your availability, relevant education, training or experience, and your area of interest.

We will then advise you whether we are able to schedule an interneeship for you, or if you are on our waiting list.

You may always send us your speculative application.

Bachelor and Master Theses

An internship is the optimal precondition for working on a Bachelor or Master thesis at HR. In order to assure a suitable supervision, the specific topic will complement current HR research activities. Appropriate branches of study are primarily in engineering and the natural sciences.

Just reply to one of the offers below or send us your speculative application.

Available Topics for Internships, Bachelor, Master Theses We offer the following topics for internships, Bachelor and Master theses. Please contact the person specified in the PDF below if you are interested.

Master Thesis or Intership: Applications Development with the 2-Look TOPS Acquisition Mode Concept 01 July 2018  available SAR acquisitions performed in burst mode allow covering wide areas by switching cyclically the radar beam in elevation. The TOPS mode introduces additionally a steering of the antenna in azimuth in order to equalize different parameters as, e.g., azimuth ambiguities or SNR. The acquisition of SAR images in burst-mode implies an azimuth resolution loss that impairs some applications as, e.g., ground monitoring in along-track direction or the retrieval of the azimuth velocity of moving targets. The two-look TOPS concept overcomes these limitations by acquiring two separated slices of the Doppler spectrum, which, if properly combined, deliver azimuth displacement estimations with even better accuracies than employing whole synthetic aperture radar strategies. The work to be performed is related to the further development of algorithms to exploit the 2-look TOPS mode for geophysical applications and for the estimation of azimuth velocities of vessels employing real SAR data from the TerraSAR-X satellite.

Master Thesis: Efficient Autofocus Techniques in Geostationary SAR Observations 15 December 2017  available The proposed work will consist of the analysis and development of efficient autofocus techniques for the recovery of residual propagation errors in GEO SAR missions, which combines the understanding of propagation physics with advanced signal processing techniques. The work will be validated with use of real data scenarios and will be conducted in the SAR Missions Group. A solid background in signal processing or programming is expected. Read more

Master Thesis: Development of an Efficient Tool for the Simulation of Radar Images of Ocean Surfaces with Real and Synthetic Apertures 15 December 2017  available The candidate shall be responsible for the design and implementation of a radar image generator of water surfaces, a task which involves radar theory, propagation aspects, linear and non-linear wave theory, and stationary and non-stationary statistical signal processing techniques.

Master Thesis: Development of an Acquisition Planning Simulator for Efficient On-Board Quantization for Interferometric and Multi-Channel SAR Systems 15 December 2017  available The objective of the proposed thesis is to develop a simulator for the acquisition planning for present and next-generation interferometric and multichannel SAR systems. For a given mission scenario (described by a set of system and acquisition parameters, such as, e.g., orbit position, beam coverage, antenna characteristics), algorithms will be implemented.

Master Thesis: Assessment of Image Quality of Waveform-Encoded Synthetic Aperture Radar Using Real Satellite Data 15 December 2017  available Starting from real satellite SAR images, acquired e.g., by the German satellites TerraSAR-X and TanDEM-X, you will simulate waveform-encoded SAR raw data for different sets of system parameters, perform the required multi-focus post-processing, and assess the image quality of the resulting processed data.

Master Thesis: Investigation of Ship Detection and Parameter Estimation Algorithms for Multi-channel Airborne Radar 15 December 2017  available Ship detection is one of the major applications for maritime security and surveillance. In the frame of the master thesis different ship detection and parameter estimation algorithms shall be implemented and compared, especially in terms of clutter suppression, detection and position estimation performance. For this task simulated data and real single- and multi-channel X- and L-band data acquired from DLR’s airborne sensor F-SAR shall be used. For the algorithm implementation and investigation Python programming skills are mandatory. Read more

Master Thesis: Temperature Stabilization Method for LNA and Frequency Mixer at Ka-Band Frequencies depended on Temperature for Airborne Pol-InSAR Applications 16 November 2017  available Goal of the thesis is the stabilization over temperature of a receiver module consisting mainly of a LNA and a mixer state. The dependency on temperature and other environmental conditions must be neglected. A method should be developed to stabilize the phase shift and attenuation for the receiver module. The proof of concept will be a hardware demonstrator. Read more
