Radar Workshop
Our CEO Dr. Florian Pfeiffer gives you insights about automotive radar technology covering the following topics:

  • Radar as key technology for automotive sensing
  • Radar fundamentals
  • Measurement principles for distance, velocity (Doppler) and direction of arrival
  • Automotive sensor performance (24 vs. 77/79GHz, radar vs. other sensor technologies)
  • Fundamentals of signal processing (from the input signals to high-level objects)
  • Integration of radar sensors into a vehicle
  • Radar calibration and radar cover (radome) measurement techniques

Next one-day workshop:
14th March 2019 at Gerotron in Martiensried (learn more)

Happy New Year
Thank you for your confidence and the collaboration on the same wavelength. For 2019 we wish you nothing but the best and many innovative ideas in all frequency ranges.

The right part of the picture above shows a cross polarized 77GHz radar image measured with our scanning radar system. Cross polarized means that transmit and receive antennas have orthogonal polarization (here Tx is linear vertical and Rx is linear horizontal). Thus, the transmitted electromagnetic wave can only be received if a polarization conversion occurs.
In the radar image, it can be clearly seen that the diagonal edges of the christmas tree are visible as they rotate the polarization angle. On the other hand the metal surface is completly invisible as the wave reflects without change in polarization.
In practice, polarimetric radars can acquire additional information which might be used in future automotive radar sensors to improve object classification.

CEPT opens Wifi Ch36-48 for in-vehicle usage
CEPT/ECC follows our proposal to open the Wifi band 5150-5250 MHz for in-vehicle use with a maximum transmit power of 25 mW (EIRP). Thus, automotive Wifi can be shifted from the crowded Short Range Device band (channels 149-169) to the dedicated Wifi channels 36-48. More Information on CEPT.
