Radome material quality analysis solutions from Rohde & Schwarz. Ensure your radomes & bumpers stay within demanding performance limits. Learn more here.

The differences in design, capabilities and applications of the QAR50 and the QAR50-R are explained and integration examples are shown.

Explore material characterization techniques and applications. Discover impedance analyzers and other material characterization equipment from an industry leader.

This video looks at the two hardware options available for the QAR50: horizontal and vertical polarization.

Why test & certification experts IB-Lenhardt trust Rohde & Schwarz radar measurement solutions

Because cellular V2X enables safety-critical functions, its correct operation must be ensured in demanding environments. Watch this video.

The R&S®QAR50 automotive radome tester is a tailored solution for radar integration testing to measure, analyze and evaluate the radar compatibility of radomes and bumpers.

Here we explain the measurement curves and images for different bands and clusters created by the QAR50 and how to interpret them.

This video focusses on measurement parameters such as attenuation, reflection and inhomogeneities, their importance for radar sensor performance and how to measure them with the R&S®QAR50.

This first video introduces the basic principles of microwave imaging and the R&S®QAR50 in general. This includes measurement clusters, reflection & transmission, traceability and test speed.

Here we focus on the terms calibration, normalization and verification in relation to the QAR50, what are the key considerations for each term and how to perform these important tasks.

This video is about the very beginning of bumper and radome measurement: material characterization. It compares the QAR50 microwave imaging solution with a quasi-optical vector network analyzer and shows how the optimum thickness of a radome can be calculated. .

Together with its partner Löhnert Elektronik, Rohde & Schwarz has introduced a fully automated turnkey solution for bumper production radar transparency testing based on the successful R&S QAR50. The lightweight and compact setup of the R&S QAR50-R facilitates precise positioning of the measurement antennas, allowing faster, more accurate and convenient testing. This leads to higher throughput and yeilds as well as more flexiblity to adapt to different DUTs, for End-of-line (EOL) measurements of bumpers and other exterior parts.

Use this option to understand the variation of transmission and reflection characteristics against frequency and check the resonant frequency is in the middle of the automotive radar band. This information can be used to adapt the thickness of the material and to calculate permittivity. It has particular advantages for sample analysis in production.

For larger samples such as grills or bumpers, it might be more applicable to move the sample instead of the measurement device. Therefore, the QAR50-R was developed. Follow me on a visit to our Partner Löhnert Elektronik where the QAR50-R is produced.

Precise insertion phase measurements with reference to a mask to detect anomalies such as injection moulding points, inconsistent paint thickness or material inhomogeneities..

This video uses the quasi-optical certified calibration setup to illustrate how the accreditation values are generated, explains its benefits and limitations. Then we compare the uncertainty with the QAR50-Z44 verification set.
