Abstract :
We investigate the problem of tracking a moving target in urban terrain using a multiple-input and multiple-output (MIMO) radar system. Our proposed method aims to maximize the target information using an optimal configuration of MIMO widely-separated radar sensors while exploiting multipath returns from all the sensors. Furthermore, we adaptively configure the parameters of the transmit waveforms of the MIMO system at each time step in order to minimize the overall mean-squared tracking error. We demonstrate our results using a realistic urban environment, by varying the regions of obscuration and the number of bounce path returns. An important advantage of the MIMO system is that, based on the radar configuration, it is possible to completely eliminate the obscuration regions.
