A Primer on Data Association
Prof. Peter Willett
ECE Dept., University of Connecticut
IEEE AESS Distinguished Lecturer
Abstract: To thread measurements (well, many call them “hits” or “plots”) of radar, sonar or imaging observations to a credible, smooth and reportable trajectory requires a filter. We’ll discuss those – Kalman, Unscented, particle, etc. – briefly. But the main topic here arises because one cannot even begin to filter without knowing which hits come from which targets, and which hits are complete nonsense (clutter). When wrapped inside some scheme for such data-association, a filter becomes a tracker. This talk is intended to explain, at a fairly high level, the intuition behind some of the popular tracking algorithms.
Cognitive Radars: Some Applications
Prof. Maria S. Greco, University of Pisa, Italy
IEEE AESS Distinguished Lecturer
The idea of cognitive radars has been introduced the first time by S. Haykin in 2006, even though the first papers on knowledge-based systems, the foundations of the modern concept of cognitive radars, trace back to the late 90'. Quoting prof. Haykin, "a cognitive radar continuously learns about the environment through experience gained from interaction with the environment, the transmitter adjust its illumination of the environment in an intelligent manner, the whole radar system constitutes a dynamic closed feedback loop encompassing the transmitter, environment, and receiver". So, the new feature of a cognitive radar that differentiates it from the classical radar is the feedback between receiver and transmitter; the classical concept of adaptivity, already known in the radar community since the early 60', is extended to the transmitter. This talk will describe some applications of "cognition" to active radars, where the need of the new cognition paradigm is motivated by the increasing erosion of the spectrum portion dedicated to them, and to passive radars although, contrary to the active ones, they cannot directly change on-the-fly the transmitted waveforms.
