Radomes and Bumpers

Automotive radome and bumper testing

Ensuring the quality of radomes and bumpers

Automotive radars are usually mounted behind bumpers or radomes and the material RF transmission and reflection characteristics effect 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.
