Workshops

1. SAR Imaging for Beginners - I

This workshop deals with the processing of SAR data. At the beginning of the workshop a SAR simulator will be developed. A range Doppler algorithm will be implemented to process the simulated raw data and also real radar data acquired with the radar system AER II. The impact of target motion on SAR focusing will be investigated as well.

4. Interferometric SAR

The workshop will focus on crucial aspects of Interferometric SAR systems. Exercises on real dataset samples will be addressed in order to investigate the aspects related to interferometric and differential interferometric processing. This involves practical works on the generation of interferograms and coherence maps. Furthermore, common band filtering for mitigation of effects of spatial decorrelation will be addressed, still in the framework of a real data experiment, to assimilate the concepts and characteristic parameter of SAR interferometric processing. Finally, a focus on the differential interferometry aspects will conclude the workshop.

5. Antenna front-end aspects of radar system design

The workshop will focus on several crucial aspects that have to be considered when designing a pulsed radar system with active electronically steered array antenna. On the basis of genuine specifications for commercial maritime navigation radar systems topics like array antennas, feeding networks, radar pulse shape, power budget, and noise will be addressed.

Research Interests: Electromagnetic Modelling, Conformal Antennas, Metamaterials, Low-Cost and Alternative Beam Scanning Techniques

6. Bistatic Radar - A work in progress

This workshop sets the scene for a fictional scenario that requires use of a radar for the surveillance of a site of strategic significance and value. The tasks that the radar must perform to ensure the survivability of the important site can be deduced by reading through the Mission Description; however, the precise radar operating requirements are formulated more concretely towards the end of the Mission Description. For reasons that will become apparent in the Mission Description, a Passive Bistatic Radar (PBR) using illuminators of opportunity is the air surveillance solution most favoured for the protection of the important site in this particular example.
This workshop provides a detailed description of the surveillance problem and states the reasons why a bistatic radar is considered for deployment. All the relevant theory necessary to complete this workshop is presented in the accompanying lecture slides.
The working group will be tasked with evaluating the potential performance of a bistatic radar to address the stated requirements. Tasks will include a theoretical analysis of the signals of opportunity and the advantages and disadvantages of each. The theoretical detection range will be calculated for the different transmitters for given probabilities of detection and false-alarm. Furthermore, as a result of heavy industry operating close to the radar site, the interference floor of the system increases, thereby decreasing the radar sensitivity. Detection ranges will have to be re-evaluated in this context.
The tasks in this workshop will exercise most to the practical considerations that must be undertaken with a passive radar design. The level of Direct Signal Interference (DSI) will have to be estimated as well as methods for its suppression. Transmit antenna beam-tilt may limit the detection of high-altitude targets and this too will have to be analysed.
The tasks in this workshop are tailored to be completed by those who have no particular prior knowledge of bistatic radar systems. However, by the end of the workshop the participants should have a solid comprehension of the principles and practice of bistatic radar.

7. Polarimetric SA

This workshop will focus on practical hands-on problems to gain a deeper understanding of the underlying theory and analysis techniques of Polarimetric SAR data and its benefit for multi-parameter environmental remote sensing. Various ideas and concepts will be addressed such as coherent and incoherent decomposition techniques. The main aim of the workshop is to increase the interest and research competence of each participant in the field of Synthetic Aperture Radar Polarimetry.
