Narrow-band SAR systems are capable of operating with very low peak power, which simplifies system design and reduce costs. In the framework of a theoretical study of narrow-band SAR systems, the candidate will be asked to analyse the trade-offs involved in the design of the system, especially for spaceborne cases, in terms of geometrical resolution, coverage, and sensitivity. The ambiguity function of the system will be investigated. To support the theoretical analysis, the candidate will develop a narrow-band SAR raw data simulator and an efficient SAR image formation kernel. Based on the previous results, the work includes the design of an exemplary spaceborne narrow-band SAR mission with identification of potential applications. Depending on the ability to cover the previous aspects of the work, there exists the possibility of validating the theoretical investigations with data gathered with DLR's airborne F-SAR and the satellite constellation TanDEM-X.
