Emblem/Radar cover Evaluation System

Model No. EES-01A
1. Quick Evaluation System for Radar Alignment(less than 2 seconds)
2. Applicable to mass production line
[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.

👉NOTE:This is FMCW Type, and CW Type also is available!

Improvement of measurement precision by FMCW radar

To secure the precision of measuring automotive emblems, it is critically important to reduce standing waves. However, standing waves are more likely to occur due to mounting angle of emblems.

Against this background, KEYCOM has changed radar transmission method from CW to FMCW, to succeed in enhancing measurement precision.
