Calibration and Direction-of-Arrival Estimation of Millimeter-Wave Radars: A Practical Introduction.

Have you read everything about direction-of-arrival estimation in textbooks but are still uncertain how to realize it in practice? This tutorial-like article will help to link the theory with a practical approach for direction-of-arrival estimation using millimeter-wave (mm-wave) radar systems, and it deals with arising challenges. Step by step, it is explained how to move from the measured time domain data to the estimated angular position of the target. Since the target angle estimation is usually carried out after range-velocity processing, the required preprocessing steps are described. [ABSTRACT FROM AUTHOR]
