摘要: 本文提出一種基于相控陣單通道接收機(jī)系統(tǒng)的波達(dá)方向(DOA)高分辨跟蹤算法。這種跟蹤算法是用特定權(quán)實(shí)現(xiàn)單通道接收機(jī)高分辨測(cè)向的進(jìn)一步完善。在信號(hào)源不相關(guān)的情況下,通過(guò)對(duì)權(quán)矢量的循環(huán)使用和功率信號(hào)的更新處理,實(shí)現(xiàn)對(duì)DOA時(shí)變信號(hào)源的跟蹤。計(jì)算機(jī)模擬結(jié)果表明該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.
