Rohde & Schwarz has enhanced its R&S QAR quality automotive radome tester, a tailored solution for radar integration testing to analyze and evaluate the radar compatibility of radomes and bumpers. With the new R&S QAR-K50 single-cluster measurement software, OEMs and tier 1 suppliers are able to achieve measurement results very close to those obtained with a vector network analyzer (VNA) and a quasi-optical (QO) setup, but in a nondestructive and 2-dimensional way. In addition, users benefit from the intuitive R&S QAR operating concept.

Automotive Radar, advanced driver-assistance systems , Why test & certification experts IB-Lenhardt trust Rohde & Schwarz radar measurement solutions

Application video: QAR50-R robotic solution 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.

QAR50 Videoseries, Measurement results in detail Here we explain the measurement curves and images for different bands and clusters created by the QAR50 and how to interpret them.

QAR50 Videoseries, QAR50-K20 Phase mask measurement Precise insertion phase measurements with reference to a mask to detect anomalies such as injection moulding points, inconsistent paint thickness or material inhomogeneities..

QAR50 Videoseries 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.

QAR50 Videoseries, Radome parameters and their effect 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.

QAR50 Videoseries, Calibration, normalization and verification 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.

Then we compare the uncertainty with the QAR50-Z44 verification set. 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.

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. QAR50 Videoseries, Material characterization This video is about the very beginning of bumper and radome measurement: material characterization.

QAR50 Videoseries, QAR50-K10 Frequency response 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.

User manual for the R&S®RadEsT radar essential tester describes how to install and operate the R&S®QAR50.

Discover why the R&S®QAR50 is the perfect tool for measuring automotive radomes and bumpers throughout the development lifecycle. From early R&D and material characterization through the complex molding processes of design emblems until end-of-line production testing.
