Key facts

  • In-band OTA measurements of 77/79 GHz automotive radar sensors
  • CATR with bidirectional parabolic reflector and a 1.3 m2 footprint
  • For testing radar modules with apertures up to 30 cm
  • High speed, high precision 3D tilt-tilt positioner
  • Ultra low reflectivity and exceptional shielding effectiveness

A must-have test solution for up-and-coming automotive radar sensors

Transportable CATR based fully anechoic chamber with best-in-class performance

The R&S®ATS1500C antenna test chamber is a compact antenna test range (CATR), consisting of a gold-plated parabolic reflector and a two-axis positioner for 3D movements of the DUT. When combined with the R&S®AREG800A and other state-of-the-art Rohde & Schwarz test and measuring instruments, it can be used for a variety of applications, including antenna characterization, radar validation, interference testing, ETSI RED and FCC in-band precompliance testing and angular calibration. The frontend antenna of the R&S®AREG800A is directly integrated as a feed antenna. The chamber can also be equipped with a universal feed antenna (60 GHz to 90 GHz) that allows the chamber to be used either with the R&S®AREG800A or via a universal WR12 waveguide feedthrough with other test instruments such as a signal and spectrum analyzers.

Features & benefits

Far-field conditions in a compact chamber

State-of-the-art CATR reflector enabling indirect far-field measurements

When measuring antenna characteristics of a 77/79 GHz 4D imaging radar with an aperture of 10 cm, far-field conditions start at > 5 m. Instead of measuring in large, fixed chambers, the R&S®ATS1500C with a 1.3 m2 footprint can measure far-field antenna characteristics thanks to its parabolic CATR reflector. The reflector is expertly designed and manufactured to create a large 30 cm diameter quiet zone and works bidirectionally.

R&D, calibration and validation

Wide range of applications to get the most out of the radar sensor

In combination with the R&S®AREG800A automotive radar echo generator, the test system can simulate highly accurate targets with variable range, velocity and RCS. The fast and precise 3D positioner mimics operating radar sensors and ensures high ,measurement repeatability. The solution is an ideal test system for radar validation and calibration. 
Additional test instruments can be added to measure antenna patterns, EIRP, operating frequency range etc. or to test receiver stability when faced with interferers.

Premium chamber quality

High shielding effectiveness and best-in-class absorbers for low reflections

The R&S®ATS1500C is a fully anechoic chamber with shielding effectiveness of > 90 dB. The best-in-class pyramidal absorbers and optimized layout significantly reduce the number of ghost targets for an deal testing environment for extremely sensitive high-end automotive radars.

High speed, high accuracy positioner

The prerequisite for precise angular measurements

The tilt-tilt 3D positioner is tailored for single polarized automotive radar testing. The adjustable height makes sure the DUT is always aligned and located at the center of rotation. The large tilt angle in both axes fulfills automotive radar requirements and features an angular resolution of 0.03° for precise measurements and radar calibration.

Convenience and flexibility

Wide variety of communications interfaces and feedthroughs

A straightforward web GUI is available to control the 3D positioner. It can also be controlled via Ethernet using simple SCPI-like commands, making it very easy to integrate into your software. Several feedthrough types are also available, providing the flexibility to accommodate DUTs with different requirements. This fulfills your testing needs without compromising the shielding effectiveness of the chamber.
