Nevertheless, the digital modulation scheme phase-modulated continuous wave (PMCW) has recently attracted considerable interest due to advantages such as high maximum unambiguous velocities. However, there remains a need for more thorough performance assessments comparing these waveforms in dynamic automotive scenarios. This work presents a flexible framework comprising a ray-tracing simulator and radar models for efficient automotive scenario generation and radar simulation. Using this framework, the performance of FMCW and PMCW radar systems is assessed in a typical automotive scenario. The evaluation demonstrates that the PMCW radar system exhibits superior performance in terms of target detectability in the given scenario.}, language = {en} }
