This contribution deals with a radar target simulator (RTS) for continuous-wave (CW) radar applications. It relies on an attenuator-based vector modulator directly operating at the carrier frequency of the CW radar without requiring auxiliary local oscillator signals as well as down- and upconverters. Based on a calibration, the RTS adjusts arbitrary phase shifts and amplitude levels in a dynamic range of at least 40 dB enabling the replay of signal modulations introduced in real-world applications. Validation measurements of a 24-GHz prototype prove the effectiveness of the concept in characterizing the performance of CW radar sensors and demonstrate its capability to emulate real-world physical targets, which is demonstrated for the example of vital-sign sensing.
