In order to test and verify radar-based systems for advanced driver assistance systems, radar target simulators offer a test environment for reproducible dynamic automotive scenarios. This article presents a system capable of generating multiple targets with individual ranges and velocities for chirp-sequence frequency modulated continuous waveform radars. The novel approach allows to generate targets without prior knowledge about the radar sensor by estimating the radar’s waveform parameters. The proposed simulator offers high flexibility at low costs by performing the estimation on undersampled data. Finally, an automotive scenario of a spatially extended target is simulated for a radar sensor with the proposed system.
