用matlab实现窄带信号的测向算法，可实现的-using Matlab achieve narrowband signal to the test algorithm, achievable

单频信号经过多径时变信道后，输出信号的包络随时间随机起伏，输出信号的频谱从冲激谱变成一个窄带频谱。径数位20，变化频率从0—2HZ随机均匀抽取。-Single-frequency signal through time-varying multipath channel, the output signal envelope random fluctuations over time, the output signal from the impulse of the spectrum into

对窄带信号进行临界采样，采用重构算法恢复原信号-sample the narrowband signal and reconstruct signal

用循环矩阵求逆非均匀窄带信号的重建方法，给出了仿真结果-rebuilding of band signal with the method of inverse the recycle array
