The development of Highly Automated Driving (HAD) systems is necessary for automated vehicles in termsof various complex functionalities. HAD systems consist of complex structures containing different types ofsensors. The functionality of HAD systems needs be tested to ensure the overall safety of automated vehicles.Methods such as real-world testing require a large number of driving miles and are enormously expensive andtime-consuming. Therefore, simulation-based testing is widely accepted and applicable in the development ofHAD systems, including sensor performance improvement. In order to identify the functional insufficiencyof such sensors that affect the safety of HAD systems, it is critical to test these sensors extensively under avariety of conditions such as, road types, environment and traffic situations. Based on this motivation, the maincontributions of this paper are as follows: First, a simulation-based test concept of radar sensors with methodsfor the Safety Of the Intended Functionality (SOTIF) use case is presented. Second, a specific radar effect isevaluated through simulation-based testing of two different radar models to support and realize the sensor’sfunctional insufficiency. Finally, the development of a filter is proposed to improve the sensor performanceconsidering the radar specific multipath propagation effects.
