TY - CHAP U1 - Konferenzveröffentlichung A1 - Kodari, Rakesh Yadav A1 - Rösch, Markus A1 - Harter, Marlene T1 - Analysis of Amplitude and Phase Errors in Digital-Beamforming Radars for Automotive Applications T2 - 2020 21st International Radar Symposium (IRS) N2 - Fundamentally, automotive radar sensors with Digital-Beamforming (DBF) use several transmitter and receiver antennas to measure the direction of the target. However, hardware imperfections, tolerances in the feeding lines of the antennas, coupling effects as well as temperature changes and ageing will cause amplitude and phase errors. These errors can lead to misinterpretation of the data and result in hazardous actions of the autonomous system. First, the impact of amplitude and phase errors on angular estimation is discussed and analyzed by simulations. The results are compared with the measured errors of a real radar sensor. Further, a calibration method is implemented and evaluated by measurements.
