Emblem/Radar cover Evaluation System

Model No. EES12-01

The system can measure transmission attenuation and tilt angle of each irradiation point on the sample such as an emblem in the following cases.

  1. when the sample moves in any direction(Azimath, Range, Elevation)
  2. when the sample rotates vertically and horizontally
[Option] Reflection measurement inside front grille
Radar waves from an automotive radar are multiply reflected on objects inside front grille such as a radar cover to be emitted forward. And the multiple reflection disturbs the waves.
Therefore, it is also important to measure the amount of such reflections, and KEYCOM can offer an optional measurement system.
