摘要
讨论了均匀圆阵中宽带信号的谱估计问题。将目标带宽分成若干个不重叠的子频带,并将时延抽头模型方法用于均匀圆阵宽带信号的采集中,然后用MUSIC算法估计信号的来波方向。仿真结果表明该方法的有效性。
Discussed the uniform circular array of broadband signal spectrum estimation. The target bandwidth is divided into several sub-bands do not overlap, and delay-tap model method for uniform circular array of broadband signal acquisition, and then use the MUSIC algorithm for signal DOA estimation. Simulation results show that the method is effective.
