摘要
本文给出了一种基于稀疏表示和可变网格技术的宽带DOA估计方法。仿真结果表明这种方法与基于相干信号子空间思想的TCT算法的估计精度相同,但它明显提高了计算效率。
This pape presents a wideband DOA estimation method based on sparse representations by using off-grid technique. Simulation results demonstrate the proposed method has the same estimation accuracy performance as TCT, one of the most classic focusing algorithms based on coherent signal subspace method （CSM）. But the calculation efficiency is greatly improved.
