With our eFence concept, we want to detect and locate road users being not equipped with any communication device. To illuminate these non-cooperative users, we use arbitrary signals emitted from communication infrastructure located along the road side, i.e. road side units (RSUs). Spanning a network of transceivers, these RSUs form a multiple-input multiple-output radar, which allows to estimate the position and velocity of the targeted users.
In our current work, we investigate an optimal signal design for the parameter estimation, and an optimal system geometry regarding target localization. Furthermore, we work on algorithms for detecting, locating, and tracking of non-cooperative users.
