Multi target simulator for automotive radar sensors with unknown chirp-sequence modulation

In order to test and verify radar based systems for advanced driver assistance systems (ADAS), 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 (CS-FMCW) 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 spacially extended target is simulated for a radar sensor with the proposed system.
