Abstract. The electromagnetic modeling of automotive radar in various traffic scenarios and in complex high multipath environments like highways and urban areas poses enormous computational challenges that cannot be addressed using conventional simulation approaches. In this paper, we describe a hybrid methodology that combines several full-wave and asymptotic numerical techniques within a unified framework that enables near-real-time dynamical simulation of an automotive radar system in a multipath physical channel, where the positions and orientations of the radar and target(s) can change dynamically as a function of time.
