HIGH-RESOLUTIN DOA TRACKING ALGORITHM BASED ON PHASED ARRAY WITH A SINGLE CHANNEL RECEIVER
-
摘要: 本文提出一种基于相控阵单通道接收机系统的波达方向(DOA)高分辨跟踪算法。这种跟踪算法是用特定权实现单通道接收机高分辨测向的进一步完善。在信号源不相关的情况下,通过对权矢量的循环使用和功率信号的更新处理,实现对DOA时变信号源的跟踪。计算机模拟结果表明该方法具有良好的效果。Abstract: This paper presents a high-resolution DOA tracking algorithm based on phased array with a single channel receiver. It is an improved algorithm of the method using specific weights to realize high-resolution direction finding with single channel receiver. When signals are uncorrelated, by using the specific weights in turn and refreshing the power measurements continuously, the time-changed DOA of signals can be traced. The computer simulation results show that the algorithm is effective.
