The 2013 International Conference on Radar - Radar 2013 will be held in Adelaide, Australia, from 9 to 12 September 2013. The conference will be hosted at the Hotel Grand Chancellor Adelaide on Hindley. This conference represents a unique opportunity for participants in the radar industry from Australia and overseas to exchange knowledge and ideas on both the theories and practices that will drive radar technology, education and research in the coming years. CONFERENCE THEME - BEYOND ORTHODOXY: NEW PARADIGMS IN RADAR Much of the progress in radar science, technology and applications follows a path of evolutionary development as component technologies, signal processing algorithms, materials science and computational electromagnetics provide ever more efficient means of implementing the radar systems on which our modern societies depend, and improving their performance against established criteria. This evolutionary process pays immediate and predictable dividends to manufacturers and users alike. Yet, every so often, we encounter a revolutionary development in some supporting technology, or a novel idea which springs from the imagination of just one or two individuals, which changes the way we think about radar and how this form of sensing can be exploited. Such developments are infrequent but important, not only for the capabilities they provide but for the way they inspire lateral thinking and innovation. Radar 2013 welcomes contributions in all areas of radar science and engineering, but particularly encourages papers which open new avenues for exploration and force us to embrace new paradigms.
