摘要
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。
In recent decades, adaptive arrays have been widely used in wireless communications, sonar, radar, medical imaging and other fields. In practical array systems, traditional adaptive beamforming algorithms are known to degrade if some of exploited assumptions on the environment, sources, or antenna array become wrong or imprecise. Therefore, the robustness of adaptive beamforming techniques against environmental and array imperfections and uncertainties is one of the key issues. In this paper, we present an overview of recent trends and advances in the field of robust adaptive beamforming.
