Automotive Radar Channel Simulation based on a High-Resolution Backscattering Model of a Motorcyclist

Abstract

Carrying out a systematic wave propagation simulation based on the backscattering behavior of traffic objects leads to more realistic simulation results. High-resolution RCS measurements in the radial and angular domain can be used for preparing the backscattering model of the traffic objects. For this purpose, the measurement setup is explained for collecting a high number of scattering points of complex traffic objects. Subsequently, the collected scattering points are processed to introduce significant scattering centers according to their RCS patterns. Those virtual scattering centers can be employed as the simplified radar model of traffic participants in the simulation tools to speed up simulations and improve their accuracy. This paper presents the systematic wave propagation simulation steps based on the simplified radar model from the high-resolution RCS measurements.
