Automotive radars are usually mounted behind bumpers or radomes and the material RF transmission and reflection characteristics affect the performance of the radar sensor and the safety-critical system it supports. For example, radome inhomogeneity or too much attenuation will cause incorrect object distance and angular position data. Therefore, ensuring consistent material quality of the radome by accurate testing is important during the development and production process.
Radome material quality analysis solutions from Rohde & Schwarz use advanced microwave imaging techniques to make sure your radomes & bumpers stay within demanding performance limits. For larger DUT sizes such as grilles or bumpers, it might be appropriate to move the measurement equipment instead of the sample. Therefore, the QAR50-R was developed. It also has many advantages for production testing because it can serve multiple testing stations at one time.
This video was recorded at our partner Löhnert Elektronik where the QAR50-R is produced and provides an overview of the solution and its applications.
