摘要

本文讨论了小型天线阵多址多址(MIMO)雷达传感器的到达方向估计方法。在信号源定位的背景下，利用传统波束形成(CBF)、最小方差无失真响应(MVDR)或Capon方法、多重信号分类MUSIC及其修正等主要数字波束形成方法，提出了一种处理“信道-距离-速度”坐标下数据阵列的算法。并对其进行了比较分析。介绍了该方法在调频连续波(FMCW)雷达中的应用，并讨论了改善其特性的技术。

DOA Estimation in Radar Sensors with Colocated Antennas

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.
