Distributed Sensing with Software Defined Radar Platforms

Speaker: Emre Ertin,
Ohio State UniversityAbstract: There has been a surge of interest in the notion of employing large numbers of distributed sensors for applications ranging from environmental monitoring to radar surveillance to biomedical sensing. Envisioned are smart sensor nodes with on-board sensing, computation, storage and communication capability. Such sensing systems simultaneously present unprecedented opportunities and unique challenges in collaborative signal processing. A particular challenge is the need for distributed inference algorithms, which balance the limited energy, computation and communication resources with sensing objectives. In this talk we review resource-constrained signal processing problems in a probabilistic framework and focus on sensor management problem. We consider software defined radar platforms with waveform adaptive transmission capability and study the problem of sensor scheduling for maximizing extracted information from the scene. We present a game theoretic approach to distributed sensor management and compare it with the centralized solution. Next, we propose a non-parametric method for multimodal data fusion of SDR information with other sensing modalities (EO, seismic acoustic) based on generalized likelihood maps. We conclude with experimental results from a layered multimodal data collection campaign at the Ohio State University.Biography: Emre Ertin is a Research Assistant Professor with the Department of ECE and Institue for Sensing Systems at the Ohio State University.
