9:15-10:00Keynote: Thomas Strohmer
- Radar and Compressive Sensing - A Perfect Couple? -
Compressive sensing has attracted significant attention in the radar community. On the one hand the theory of compressive sensing has provided a better understanding of when and why already existing sparsity-exploiting methods in radar do work or don't work. On the other hand, insights from compressive sensing have led to substantial improvements over existing methods in some cases. But there are also some serious challenges that need to be resolved in order to reap the full benefit of techniques from compressive sensing in radar. In the first part of my talk I will focus MIMO radar. I will analyze theoretically and numerically the performance of sparsity-exploiting algorithms for the detection of targets in the azimuth-range domain and in the azimuth-range-Doppler domain. In the second part of my talk I will focus on open problems, possible road blocks, and ongoing research at the interface of compressive sensing, sparsity, and radar.

- Compressed Sensing: Application Examples in SAR Imaging -
The Compressed Sensing (CS) theory asserts that it is possible to recover certain signals and images from a number of measurements much lower than that required by traditional methods, provided that two properties are satisfied: sparsity, which pertains to the signals of interest, and incoherence, which pertains to the sensing modality. The possibility of reconstructing a signal from a reduced number of measurements can be effectively exploited in many applications in the field of radar and microwave imaging. For CS practical applications two main problems have to be faced: measurement requirements for attaining a reliable solution and determination of the maximum achievable spatial resolution from a given measurement set. Some examples in the field of Synthetic Aperture Radar (SAR) Tomography are presented and discussed, with particular reference to the above mentioned problems.
