Rohde & Schwarz Upgrades Automotive Radome Tester R&S QAR

Rohde & Schwarz has improved 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.

Rohde & SchwarzWith the new R&S QAR-K50 single-cluster measurement software, OEMs and tier 1 suppliers can achieve measurable 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. Also, users benefit from the intuitive R&S QAR operating concept.

 The R&S QAR  automotive radome tester is an mmWave imaging system for demanding radome and bumper material testing and validation. Thanks to its outstanding performance, speed, quality and intuitive operation, it is the perfect tool for applications ranging from development and production to verification of radome material and integration of 76 GHz to 81 GHz radars.

The high spatial resolution comes at the cost of having a larger spread in terms of incident angles. A typical radar sensor has a certain field of view, e.g. +/-10° for full-range (FRR) and +/-60° for short-range radars (SRR).

Derived from material characterization techniques, the reflection parameters of radomes are mainly defined for perpendicular incident angles as these parameters can be measured using VNAs. The R&S QAR-K50 software option addresses this topic.

Comparing the results delivered by the R&S QAR to those measured with a standard vector network analyzer (VNA) and a quasi-optical (QO) setup, some deviations can be seen and explained with the larger aperture used by the R&S QAR.

The R&S QAR-K50 software detects the correct measurement area by itself and provides optical feedback to the operator in case the positioning of the samples is slightly out of tolerance. The R&S QAR now combines its high-resolution image used for homogeneity analysis (R&S QAR-K10 software) with a robust and easy-to-use reflection measurement. The measurement values obtained with the R&S QAR-K50 software option are directly comparable to the results delivered by VNAs in QO setups.

The R&S QAR-K50 software option for single-cluster measurements can be installed on all Windows 10 instruments with the most recent firmware using keycode activation.
