基于多径信号衰落特性的快速DOA估计算法
A Fast DOA Estimation Algorithm Based on Multi-Path Signals Fading Characteristic
摘要
Abstract
A fast DOA estimation algorithm based on multi-path fading characteristic was put forward for the need of low-angle bearing in this paper.A new de-correlation method based temporal data block smoothing was proposed firstly,which was no array aperture losing and had no requirements to the aperture structure.Then the correlated sources and incoherent sources were resolved separately,and the temporal data block smoothing was performed iteratively utilizing smaller sensor arrays,which could reduce the computational complexity and estimate more sources.The algorithm needn＇t eigen-value decomposition and high ability of realization.The simulation results showed that the algorithm was correct and effective.关键词
