Conventional pedestrian protection systems utilizing contact or noncooperative perception sensors are limited by uncertainties in target classification. Moreover, these systems offer no benefit in case of fully or partially hidden pedestrians like e.g. children hidden by cars. In this paper, The authors present a novel approach using cooperative sensor technology to overcome these drawbacks. Within the research project AMULETT, a cooperative sensor system is developed to clearly classify and locate vulnerable road users. The system warns the driver in the early phase of a possible collision or is triggering collision mitigation strategies in case of unavoidable contact. In this paper, the cooperative sensor system is consisting of a transmitter operating the interrogation pulse, a smart antenna array determining the wave vector of the incident target response and time-of-flight measuring equipment determining the distance of the target. Moreover, decoding the modulation of the target's echo it is classified as vulnerable road user.
