基于随机理论和多级维纳滤波(MSWF)思想,提出了一种均匀圆阵列单通道快速高精度测向定位算法。该算法只用一个接收通道,与多接收通道相比,在系统成本和复杂性方面具有显著的优势,并且避免了通道间幅相不一致导致算法性能下降的问题。该算法无需对阵列接收矩阵进行特征分解,减轻了星上处理器的运算负担,星上高精度测向定位的实时性得到保证。仿真实验验证了该算法的可行性和有效性。
Based on stochastic theory and multistage Wiener filter (MSWF), a fast and accurate direction finding algorithm for single-channel uniform circular array is proposed. Compared with multi-receive channels, this algorithm has significant advantages in terms of system cost and complexity, and avoids the problem of algorithm performance degradation caused by inconsistent channels and channels. The algorithm does not need to decompose the array receiving matrix to reduce the computational burden of the on-board processor. The real-time performance of high-precision on-board DFW is assured. Simulation results show the feasibility and effectiveness of the proposed algorithm.
