Key facts

  • Extremely flexible and scalable system
  • High radial resolution and field-of-view coverage
  • 4 GHz instantaneous RF bandwidth
  • Reduced close-range reflections and multipath 
  • Elektra Award Winner

Spatial moving targets without mechanical movement

As an alternative to standard RF frontends, the R&S®QAT100 offers the possibility of generating horizontal (alternatively vertical) moving targets without requiring any physical movement. With up to 2 x 96 individually switchable transmit antennas (with R&S®QAT-B2 option), the R&S®QAT100 ensures high resolution, high speed and high repeatability. 

Its 4 GHz instantaneous RF bandwidth together with the ability to handle up to 8 completely independent objects offer the ability to simulate even densely populated scenarios.

Features & benefits

Extremely scalable and flexible

Combine several R&S®QAT100 in order to increase the field-of-view

Several R&S®QAT100 can be combined in order to increase the field-of-view (FOV). All R&S®QAT100 advanced antenna arrays in a multi-instrument setup are synchronized via the R&S®AREG800 dynamic radar echo generator. This allows the simulation of complex ADAS scenarios.

Depending on the amount of available IF-path on the backend, densely populated scenarios with up to 8 independently moving targets can be generated.

High speed and accuracy

Simulation of radial moving targets with extremely high speeds

The antenna spacing of only 3.7 mm provides a high radial resolution for realistic simulation of complex radar scenarios. Thanks to the electronic switching of the antennas, it is possible to simulate extremely fast radial velocities with an outstanding reproducibility.

The absence of moving parts and the missing necessity of moving the frontend for azimuthal object simulation result in reduced wear and tear and a high accuracy and repeatability of the simulated object angles.

Equipped with the QAT-B2 option, the R&S®QAT100 features up to 192 individually switchable transmit antennas.

Reduced close-range objects

Reducing close-range reflections to minimize interference on the radar.

The small patch antennas together with the absorber covered surface provide a clean RF frontend with very low RCS. This reduces the sensor's noise floor and potential multipath reflections.

Additionally, the R&S®QAT100 can be equipped with the R&S®QAT-B50 option, providing a shielded environment to the radar sensor and thus further reducing the potential interference with neighboring test setups.

Ready for complex scenarios

Up to 8 completely independent objects on a single frontend.

In order to simulate urban scenarios, a high object density is required. The R&S®QAT100 with R&S®QAT-B2 option supports up to 8 completely independent targets that can be directed to 192 individual antennas.

In order to decrease the complexity for the user, the R&S®AREG800 takes care of scenario generation and automatically addresses the corresponding antennas of the R&S®QAT100.

Open Lightbox

The R&S®AREG800 and R&S®QAT100 with R&S®QAT-B2 option are the best performing solution when the simulation of complex radar environments is required.
