通过虚拟阵元进行DOA估计，对于初学者具有参考意义，含噪脉冲信号进行相关检测,分析了该信号的时域、频域、倒谱，循环谱等,能量熵的计算，采用的是脉冲对消法，包括数据分析、绘图等等,包括随机梯度算法，相对梯度算法。- Conducted through virtual array DOA estimation, For beginners with a reference value, Noisy pulse correlation detection signal, Analysis of the signal time domain, frequency domain, cepstrum, cyclic spectrum, etc. Energy entropy calculation, It uses a pulse of consumer law, Data analysis, plotting, etc., Including stochastic gradient algorithm, the relative gradient algorithm.
