Adaptive waveforms selection for IMM-UKF tracking architecture: application to multifunctional radar systems in heavy cluttered scenario

Modern phased array radars are able to adaptively manage the way in which they explore the surroundings, both in the space domain (thanks to their beam steering capability) and in the time domain (via a smart selection of convenient waveforms), in order to suit a variety of environments. Multifunction radars, more than tracking radars, are in big need of an efficient way to allocate their limited resources (namely, the radar time) to a number of tasks, so that being adaptive is not only a boost for the tracking performances, but also a way to spare resources during undemanding tasks (i.e. big targets in clear areas) and reroute them towards more difficult ones.
