提出了一种基于Bessel函数的宽带相干信号子空间DOA(Direction-of-Arrival)估计方法,新方法不需要角度预估,避免了角度预估误差对DOA估计结果的影响。仿真结果证明了方法的有效性。
A new DOA estimation algorithm for wideband sources is introduced. The Bessel function expansion of the array manifold of every frequency in the signal bandwidth. not require any preliminary knowledge of the DOAs. Simulation results demonstrate the method is based on The technique does effectiveness of the method.
