Radomes and Bumpers

Radome testing

Ensuring the quality of radomes and bumpers

Automotive radars are usually mounted behind bumpers or radomes.

When selecting the materials, care must be taken to ensure good signal penetrability in the desired frequency band. The use of lower quality radomes can impair signals to such an extent that angular errors, distortions and strong signal attenuation occur.

The R&S®QAR offers the ideal way to quickly and reliably filter out lower quality bumpers and radomes in production. It furthermore features the possibility of producing spatially resolved mmWave images of the reflectivity and transmittivity of the radome material to detect inhomogeneities within the material.

The R&S®ZVA network analyzer is used to determine the relative permittivity of radome material.

Benefits of our solutions

  • Fewer failures of customer functions thanks to the higher, consistent quality of the radomes used
  • Spatially resolved analysis of transmission and reflection values within seconds

Free white paper: Fundamentals of radome and bumper measurements using the R&S®QAR

Due to design challenges, radar sensors are usually hidden behind bumpers or emblems, which can influence how well the radar sensor can interpret the outgoing and incoming data. To test radome and bumper influence on radar sensors, this white paper examines how the R&S®QAR quality automotive radome tester can help.

The QAR principle explained in a minute

When selecting plastic materials for bumpers, care must be taken to ensure good signal penetrability in the desired frequency band. The use of lower quality radomes can impair signals to such an extent that angular errors, distortions and strong signal attenuation occur.

The QAR makes these impacts visible and helps producing radomes with less impact on angular accuracy. This video demonstrates the ease of radome and bumper analysis using the R&S QAR.
