Antenna Array Processing: Autocalibration and Fast High-Resolution Methods for Automotive Radar (2012)
Abstract / truncated to 115 words
In this thesis, advanced techniques for antenna array processing are addressed. The problem of autocalibration is considered and a novel method for a two-dimensional array is developed. Moreover, practicable methods for high-resolution direction-of-arrival (DOA) estimation and detection in automotive radar are proposed. A precise model of the array response is required to maintain the performance of DOA estimation. When the sensor environment is time-varying, this can only be achieved with autocalibration. The fundamental problem of autocalibration of an unknown phase response for uniform rectangular arrays is considered. For the case with a single source, a simple and robust least squares algorithm for joint two-dimensional DOA estimation and phase calibration is developed. An identification problem is ... toggle 6 keywordsadvanced driver assistance systems – autocalibration – automotive radar – direction-of-arrival (doa) – maximum likelihood estimation – uniform rectangular array
