Abstract
The paper discusses methods for the direction of arrival estimation (DOA) in MIMO radar sensors with a small antenna array with colocated elements. An algorithm for processing a data array in the “channel-range-speed” coordinates is presented in the context of signal sources localization with the main digital beamforming methods, such as conventional beamforming (CBF), minimum variance distortion-less response (MVDR) or Capon method, multiple signal classification MUSIC and its modification. Their comparative analysis is given. The application of the methods in frequency-modulated continuous wave (FMCW) radar is shown and a technique for improving their characteristics is considered.
