摘要
波达方向估计是阵列信号处理一个重要的研究分支,广泛地应用于军事及民用领域。基于空域信号自身具备的稀疏性,压缩感知理论为窄带信号波达方向估计提供了一种新的思路。通过本文设计的仿真实验,学生可以建立远场窄带测向模型,并对基于块稀疏算法的窄带测向和相干非相干信号块稀疏混合测向仿真。
Signal direction of arrival estimation is an important research branch of array signal processing,which is widely used in military and civil fields.Based on the sparsity of spatial signals,compressed sensing theory provides a new idea for DOA estimation of narrowband signals.Through the simulation experiment designed in this paper,students can build a narrowband direction finding model in the far field,and simulate narrowband direction finding based on block sparse algorithm and coherent incoherent signal block sparse mixed direction finding.
