This paper applies the Mixture of Gaussians probabilistic model, combined with Expectation Maximization optimization to the task of summarizing three dimensional range data for a mobile robot. This provides a flexible way of dealing with uncertainties in sensor information, and allows the introduction of prior knowledge into low-level perception modules.(More)

A comparison of MTI and Optimum Pulse-Doppler processors is presented for the case where they coherently process the same number of pulses in a radar dwell. These results are presented in terms of probability of detection versus signal-to-noise or signal-to-clutter ratio, for a fixed false alarm probability. When multiple dwells are transmitted during the(More)
