中文说明：
基于宽带OFDM信号的DOA估计，采用经典的CSM算法，聚焦后采用传统MUSIC算法，最后通过谱峰搜素算法得到估计的来波角。
English Description：
Based on broadband OFDM signal DOA estimation, using the classical algorithm of CSM, focus after using traditional MUSIC algorithm, finally through the spectrum peak search algorithm to get the estimate to wave Angle.
