摘要/Abstract

摘要： 提出了一种快速跟踪移动目标的盲波束形成新算法,算法摒弃了传统的自适应波束形成算法在跟踪移动目标时,独立地进行每一次波束形成的观念,充分利用前续波束形成所提供的用户的方向信息,较大程度地加快了后续波束形成的进程,从而提高了算法跟踪移动目标的实时性.计算机模拟跟踪实验证实了它的可行性.

Abstract: A new blind beamforming algorithm to fast track several movable users was proposed in this paper. Instead of forming independent beams at different times by the conventional method, the information of the users' DOA obtained from the previous beamforming is made full use of.It can greatly speed up the subsequent beamforming and lead to enormous saving in the required real time computations.Therefore, the new beamforming algorithm could keep up with the moving targets more quickly, which is of great importance in real communication systems.Simulation results confirm our ideas.

Key words: blind adaptive beamforming, direction-of-arrival, adaptive beamforming
