Features & benefits

Dynamic target simulation

The R&S®RadEsT captures the signal from the radar sensor, modifies and returns it as a simulated radar target. The simulated target can dynamically be configured on the fly for distance (2.5 m to 250 m), velocity/doppler (0 to ±500 km/h) and attenuation/RCS (> 40 dB). This allows quick simulation of moving targets and qualification of radar sensor based autonomous driving functions, e.g. automatic emergency braking (AEB) or adaptive cruise control (ACC)

Innovative antenna design

The R&S®RadEsT has a flexible antenna design. To simulate targets from a certain angle, the R&S®RadEsT features 12 receive and 12 transmit patch antennas with different polarizations. The angle of the simulated target can be changed without mechanical movement. To deal with different radar sensors polarizations, a built-in detection mechanism can detect the antenna polarization and choose a suitable antenna pair.

Integrated analysis functionalities

With its internal analysis capabilities, the R&S®RadEsT can directly measure key indicators of radar sensor quality such as equivalent isotopically radiated power (EIRP) and occupied bandwidth.

Small form factor and light weight

The R&S®RadEsT is the most compact automotive radar target simulator with dimensions of just 186.5 mm × 138.6 mm × 275 mm (W × H × D) and weighing only 3.2 kg. This makes setup and integration in any test environment easy. Optional battery powered operation is available for even more portability and flexibility.

Self-check capability

The R&S®RadEsT features self-check capability to identify discrepancies or drifts in its performance metrics and can compare them against predefined thresholds to detect any drift or deterioration in functionality. It alerts users to deviations or abnormalities in the measurement process. This feature is crucial for maintaining reliability and precision in simulation plus analysis functions, reducing downtime and ensuring consistent performance over time.

Reduced reflections and multipath effects

Small patch antennas together with an absorber covered surface provide a clean RF frontend with very low RCS, suppressing close-range targets and potential multipath reflections.

Shielded environment for better results

To minimize reflections and provide interference-free RF environment, the R&S®RadEsT offers small and compact shielding systems. The R&S®RadEsT-Z50 pyramidal or R&S®RadEsT-Z55 straight shielding system can be used from lab to vehicle level.
