近十年自适应波束形成算法在通信、雷达、声纳、生物医学工程等科技领域中得到了极为广泛的应用。在实际应用中,如果信号源、天线阵列出现误差,传统的自适应波束形成算法性能将会下降。但是对于稳健的自适应波束形成算法,环境及天线阵列的误差和不确定性是必须要考虑的关键问题。这里对稳健的自适应波束形成算法的研究现状与发展动态进行了较为详细的评述。
Nearly ten years adaptive beamforming algorithm has been widely used in the fields of communications, radar, sonar, biomedical engineering and other fields of science and technology. In practical application, if the signal source and the antenna array are in error, the performance of the traditional adaptive beamforming algorithm will be degraded. However, for the robust adaptive beamforming algorithm, the errors and uncertainties of the environment and the antenna array are the key issues that must be considered. The current research status and development of robust adaptive beamforming algorithms are reviewed in detail here.
