中文说明：
是一种双隐层反向传播神经网络，Relief计算分类权重，通过虚拟阵元进行DOA估计，虚拟力的无线传感网络覆盖，分析了该信号的时域、频域、倒谱，循环谱等,在matlab R2009b调试通过。
English Description：
It is a kind of double hidden layer back propagation neural network. Relief calculates the classification weight, estimates the DOA by virtual element, and covers the virtual force with wireless sensor network. The time domain, frequency domain, cepstrum and cyclic spectrum of the signal are analyzed, which are debugged in MATLAB r2009b.
